Uncharted series comes back with a bang. (no spoilers)
Game Play and Story: Not much was changed except for a few motion control tweaks, kept it simple but awesome. The story was just amazing a little bit of fantasy/corruption/adventure and treasure hunting all mixed in the right amount. The character developments with the story through out the game was just exhilarating.
Graphics: by far the most advanced graphic design on any console mankind has ever witnessed, only second to or matched by God of War 3. Seamless movement from CGI to game play and vice versa.
Sound & Voice animation: there are little sound problems/misses at some parts but barely noticeable when you have something as great as what you are looking at on the screen. Voice animation was very good not the best (as I think that cake will be consumed by the new Mafia 2 game).
Overall the experience is highly exhilarating and a hell of a lot of fun. Don't give this a miss.
