Definitely want to see what kinds of games come from the new studios they acquired. Thats the last I´ll say since you seem bothered by them being discussed here.
As for Uncharted continuing, I can see why Sony doesn´t want to shelve the IP. At one point it was their biggest series and Sony was nearly dependent on it continuing to ensure they´d have a guaranteed massive console seller. But things are so different now. God of War, Spider-Man, Horizon, The Last of Us, etc. are such huge franchises that they dont really need to go out of their way to make sure they have an Uncharted on PS5 when they have a bunch of series on that level presently. Then again, it is still another 10+ million selling game they have in their fold so they aren´t going to move on from it when there is so much more they can do with the IP.
So with it selling so much and being so beloved, they probably don´t want to lose consumers who see Uncharted as one of their top reasons for buying a new PlayStation. I even have a sister who adores Uncharted and wants to see a new one for PS5.
