Max discussed this on Twitch last year.
He talks about how Ono wasn't fired, but he was demoted over the years at Capcom. What he Max doesn't say in this video (he mentioned during a Twitch stream) that SFV was going through development issues and some fighting game director of Capcom vs SNK has taken over. He also mentions that Covid has ruined Capcom plans to release this game earlier, too. Max said he has heard similar things, but didn't want to go into detail until the information was out there.
Max was wrong, same goes with the 'Ono was demoted multiple times'. One of the previous times he was supposed to be demoted, according to them Ono was also supposed to be kicked out of Street Fighter while he still continued for years as executive producer of the games, head of the Capcom fighting games, in charge of setting up Capcom's eSports and SF PR key person in interviews or events.
The thing is that there is a Capcom IR page where they show changes in roles or duties for executives and some of these 'insiders' misundertand what is explained there and always said 'hey Ono was demoted'. Example: Ono had a duty that was to create the eSports division, once the division was created his role was done there so they removed that duty.
They changed the job role naming of the CEO of the Capcom USA subsidiary in charge of merch licensing and eSports for USA to reflect her new position inside this new division and same for the guy who handled the Capcom eSports in Japan even if they would continue doing the same job they did before the division was created. Some idiot turned it into "Ono has been demoted and has been replaced by a well known female in the eSports scene as SF6 director" and many people believed him because liked to throw shit to Ono or SF. When she wasn't replacing Ono, it wasn't related to SF6 at all, Ono wasn't working as director and this woman doesn't even work in Japan and isn't related to game development at all: she runs a USA specific subsidiary to license Capcom IPs and eSports.
Same goes when they merged two Capcom Japan R&D divisions, the one known for the fighting games and the one known for Monster Hunter. If you go to check the game credits of Capcom games of the last generations, you'll see there that their different divisions already share staff. Like 100 devs who worked at SFV also worked at DMCV, RE7, RE2, MHW and so on. These divisions were already working together, so to merge them would reduce paperwork and would make it more productive. Ono already had many other duties in addition to executive producing Capcom's fighting games and managing that division, and was going to start a new big one of creating the eSports divisions and to start setting the big Capcom eSports plans. The manager of the other division instead had less duties and had a higher job rank in the company so he became the manager of the merged division instead of Ono.
Some idiot saw the job title/job duties change on that page and said 'Ono has been demoted and kicked out of Street Fighter, now the Monster Hunter guy will be in charge of Street Fighter' and again many people believed him, while in reality Ono continued doing his same job as SFV executive producer and other Capcom Fighting games, guy in charge of the SF series, guy in charge of the eSports and so on. Capcom even recognized Ono's work in their Capcom yearly report cover story highlighting his work with eSports and the SFV comeback, setting this above MHW achieving the 'best selling Capcom game ever' milestone.
Ono or other Capcom people mentioned even since launch that they planned to support SFV 'until at least 2020' but that it would depend on performance/player support and that they would like to support SFV series as long as they supported SFIV series. Several times. Around a year and a half Ono in SFV Q&A panels at EGX or Brazil Game Show (remember, Ono according to the idiots was demoted and kicked out from SF) said they will continue supporting SFV for as long as they supported SFIV series, that still had many things on store for SFV -as it was SFVCE, more characters, costumes and stages, new mechanic, etc- and that they wouldn't release SF6 before being done with SF5. He also mentioned that before designing the next SF (SF6) they wanted to see PS5 and the first next gen games in the market to see how they could take advantage of the new technologies and features to take advantage of them in fighting games, said that as they did before wanted to take their time after the console release and didn't want to rush SF6 in order to don't repeat the issues they had at SFV launch.
So if you count a couple of years of full production since PS5 launch you get a potential late 2022 SF6 release. The time elapsed between PS3 and SFIV releases are the same time elapse between PS4 and SFV releases. If you add that time to the PS5 release you get a potential release on Q1 2023. If you add to the SFV release the amount of time elapsed between SFIV and SFV releases, you get a potential SF6 release in Q1 2023.
Guess what, the leaked Capcom document with their future roadmap mentioned SF6 estimated release for Q4 2022. Delays are very common in game development, so consider it may be delayed to 2023 specially with covid. So matches perfectly Ono's words made years before, some from 2019 and other ones back to 2015/2016 when the game was announced or released.
That leaked document was from before that fake 'Ono was demoted again, replaced from SF6 direction, the game was planned for 2021 but has been delayed because they didn't like etc' rumor. The whole SFVI is planned to 2021 thing doesn't have any real insider info, it comes from some fan's assumption that many people made from a Capcom Cup 2020 rule change, where the winner wouldn't clasify to 2021 and they thought it meant SF6 was going to be released in 2021 (even if that would be contrary to all publicly mentioned Capcom plans for SFV and SF6) because in the only Capcom Cup were the winner wasn't clasified to the next year edition was the year they jumped from SFIV series to SFV. But in reality, Capcom changed several other Capcom Pro Tour and Capcom Cup rules, and did it multiple times this year and the previous ones. In fact, they changed them again a few days ago.
But for some reason for the idiots this rule was like some kind of sacred thing that even if Capcom changed all the other Capcom Pro Tour and Capcom Cup rules and stated multiple times that they will continue supporting SFV for years before releasing SF6, the rule must continue as a sacred thing there and that if the winner wouldn't clasify it must be because that year they release the game because the sacred religious dogma says so. When the reality was that it was a random rule change as the many other ones they made this and the other years and never had planned SF6 for 2021.
Regarding 'Capcom vs SNK director', I assume he was just mentioning his fan wishes. I'd love to see him directing SF6 but it won't happen. I think he meant Hideaki Itsuno, CvS2 director (the first one didn't have 'director', had producers who aren't at Capcom and its main game designer was Itsuno). Itsuno recently directed Devil May Cry 5 and DMC5 Special Edition, and his next game very likely will be Dragon's Dogma 2, scheduled in the Capcom leak for Q2 FY2022 (Jul-Sep 2022) and a project that he mentioned many times he wants to do (he also directed Dragon's Dogma).
I think the SF6 team would be pretty likely the same as the current SFV team. When Ono said they weren't going to move to SF6 until done with SF5, sounds like the team would be the same (so the game would be developed in addition of some months without SFV content before SF6, the last content of SF5 would be done by a part of its team while the other would be developing SF6 on a paralel track. There are a few leaked SF6 related Capcom emails, and they are between game art outsourcing companies who already worked with them for SFV (Streamline Studios or Ningbo Xiji Animation Digital Game), a 3 Capcom people being one of the 3 Assistant Manager that SFV had.
