Yeah, it seems to be a couple of new games mixed with collections and remasters at present.
I admittedly haven't played Uncharted 4, but my understanding is that it's 100% the final game in the series, so unless they do prequels, I can't see Uncharted coming back.
Last of Us I can see lasting longer, especially with how successful it is at present, though ironically there's more remasters than new games in the series now.
Personly, I'd love to see a new IP similar to Crash, though that's more the kid in me wanting that. If they do a new one, I wouldn't be surprised if it's something similar to Uncharted or Last of Us but with something a little different (ie. both are technically adventure games, though Uncharted is more action and Last of Us is more survival horror).
