That 'rumor' doesn't make any sense, like the assumption that SFVI was going to be released next year because one out of the a lot of CPT/Capcom Cup 2020 rules they changed lead to think that.
Capcom said last year:
-They plan to keep supporting SFV for a while, about the same time they supported SFIV series (~7 years)
-They won't start SFVI until they are done developing SFV stuff
-They want to see the first next gen games in the market to see what next gen can offer to the fighting games and design the next SF (VI) around it
-They won't be able to start working on SFVI at all if lucky this or next year
-They are aware of the issues they experienced with SFV launch and don't want to repeat them, so won't rush SFVI launch
-And they didn't mentioned it, but once they start to develop a game they need 2 or 3 years to release it, so don't expect SFVI release until 2023 or so
They also mentioned that initally they planned to have a softer season V, but due to the big player support of season 4 and specially SFVCE, they decided to put more resources and content into season V.
