I could totally see this happening at a December 3rd, 30th anniversary PlayStation Showcase. We still haven't seen any 30th Anniversary stuff from Herman Hulst, the co-CEO of SIE. He was completely absent from the State of Play in September.
I could imagine we could see the following
Wolverine
Ghost of Yotei
Death Stranding 2
Marathon
Venom
Current Gen Only - MLB The Show
Fairgames
and even GTA6... if Sony actually has a marketing deal with them. With the exception of Wolverine all of these games are supposed to come out in 2025. With there being no more e3, there is probably a time in which showing these at the same time merits value and I think it may be on the earlier side if you're looking to avoid release dates next to GTA6.
We know most of these games aren't releasing Q12025 (Fairgames could) and they'll probably avoid Q42025. So at least five games (not including MLB) in 6 months (more or less)...
Then there are the obvious games we haven't seen or heard much about
Naughty Dog's game(s)
Cory Barlog's game
Bend Studio
Bluepoint
Media Molecule
