Big Insomniac fan here.
I personally believe that Ratchet is a launch window title. Hopefully it arrives on the system within 6 months of it's launch. Same goes for Demon Souls.
Either ratchet is December or early Q1. I mean menu system, cutscene to gameplay and then showing extended gameplay that had a lot of things looking far along. And remember ratchet and clank 2016 was made in like 10 months. This is why even with covid I think we are going to see both their games for launch/launch window.
When Sony does another state of play it will be a deep dive on miles, bugsnax, and a montage of games with their release dates.
The cut off point in all honesty when looking at things is literally end of this month for retailers. Already we have controllers from MS leaking that have ship boxes with street date stickers. I worked retail for 10 years and did many launches. Basically we would have to have things in our PO system minimum of 4-8 weeks before release.
Sony has a plan, and I think closer to the end of this month going into TGS time, they will reveal more.
DC has their fan-dome next week. Which is around the time it was originally rumored for a Playstation state of play or event. I also believe if Sony still has a deal with Warner bros we will see the harry potter game and montreal batman game.
