Nolan North, voice actor for Uncharted’s Nathan Drake (and a gazillion other games), have seen stuff running on PS4 that is “extraordinary”. In an interview with GamerHub he said this:
I’ve seen of the prototypes of the PS4 and I know that a lot of the developers I’m working with that use the PS4… it’s an amazing machine. I think it’s going to step up the game for any game. Whether it’s Uncharted, God of War, Call of Duty, all these games are going to benefit from just the technology that they’re putting out.
When we think we’ve reached the pinnacle of what a game can look like, some genius somewhere makes it a little bit better and opens up the avenue for an opportunity to make the game more cinematic, more of an experience. I think the PS4 is going to be pretty amazing – it’s going to push those boundaries even further.
I’ve seen some stuff… gameplay… that they’re testing for… I don’t remember what game it was but they were doing some testing on the PS4 and I couldn’t believe it was gameplay. I mean, it’s extraordinary technology.
