Uncharted 2 wasn't on my radar, but now...it's day 1. The first one didn't impress me, but this one looks fantastic. Hopefully the game play won't be a downgrade from the original aka R1/R2.
Of course, if Naughty Dog was making a 360/PS3 game, it would probably look better than any other multiplatform game...and most exclusives. Probably a few exclusive PS3 games like GT5, KZ2, etc., looking better, and maybe Gears 2 or something...although I'm not the biggest fan of UE3.0. ND is probably a top 5 studio when it comes to visuals IMO. But yeah, Sony's studios are doing a great job of utilizing the PS3's hardware. MGS4 was a 3rd party game which did get the best graphics award, but being a PS3 exclusive, it wasn't too far off from being 1st party (although Sony's 1st party studios seem to be a bit better on the technical side of things).
Naughty Dog and Insomniac share their code and have been kind of sibling studios, including sharing consultants like Mark Cerny. They both have always had games that looked better than the stuff being released by other studios at the time. Looking forward to Uncharted 2 and the new Ratchet & Clank. Especially now that I have an HDTV. The game I'm still looking forward to the most is Brutal Legend. It might not have the best graphics, but Tim Shafer games are always my favorites.
