Seeing as its a sequel to a new IP on PS3 it doesn't have the impact with previous Sony owners that an established game has that was on the PS2 or PS1.
Gran Turismo 5, Final Fantasy XIII, and God of War III on the other hand should push systems well over 300,000. Probably by an additional 300,000. One of my friends bought the slim because he knows he absolutely cannot miss out on God of War III. He'll be buying Uncharted 2 in the meantime though :)
Uncharted 2 may not be the biggest driver for people to pick up a PS3 this year, but it should sell a lot of games. I think it will be 2nd place to only Modern Warfare 2.
So 300,000 consoles sold Uncharted 2 week 1? Sure, why not? I'm basing that off the sales week for Oct 3rd 2009 and it would be only a 63,000 increase. Not huge, but this game is carrying lots of hype so I think its possible. I'll guess 320,000 the week that Uncharted 2 releases. So approximately 83,000 increase.
