In an interview with Gameblog.fr, Naughty Dog co-president, Christophe Balestra, reveals a sliver of details concerning their flagship franchise's entrance into Sony's upcoming NGP console.
The game will take place between the events of the first and second game. It is also said to have some form of cross-interaction with the highly anticipated Uncharted 3. Since the game is designed for a handheld, it'll have a different "vibe" and rhythm from its console brethren. Not to mention, there is apparently more exploration involved than its predecessors.
Watch the interview below. It's all in French, however.
