Not yet but no doubt it will do eventually. There was about a year and a half between PS4 and PC releases for Remake. There has barely been 6 months gone since Rebirth was release, and I’d expect it to be about the same time period.
They might speed it up though since square said they're moving away from exclusives where possible. FFVII Remake team have six they will focus on ps5 just to set such big games quicker initially. But square would be stupid to not have a second team working alongside them to port both the second and third. With the third hopefully being closer to release if they follow this strategy.
it just came out of exclusivity at the start of the summer and 16 will probably come out first (since i'm sure they won't release them at the same time). i can't wait to get it for my steam deck though even though i've already played it on ps5 :)
Considering sales of 2 were far below their expectations, I thought they'd be scaling back 3. At any rate, swing big or go home. Or conversely, maybe keep expectations in check?
