Well STALKER 2 is already confirmed to be using UE5 so the ball is already picking up speed. I just hope GSC follow 4A and move the main studio out of Ukraine for the foreseeable future.
Well I could have said fortnite being first but that imho isn't a game LUL
Loads will come out either end of year or early next i feel, they have all been working together on UE5 for a long time now, so i'd expect when the next round of anouncments come around we'll hear about lots of them.
