The original Uncharted launched back in December 2007. It was a good holiday season for the PS3, but it was still lagging behind in sales. It wasn't even at 10 million. The game also kind of came out of nowhere- it was a new IP.
The launch week was horrendous, it just broke 100k units (mostly due to a broken street date I believe). However, it sold 100k+ for nearly 10 weeks, and had great legs. It was finally bundled and hit 2.5 million, and is on the way to selling more.
Uncharted 2 has gotten a lot more hype because of the quality of the original game. It's been winning best of E3 awards and getting loads of coverage from gaming websites. Of course, they've improved on the original- online multiplayer, improved graphics and animations, more gameplay variety, you name it. This should also be a great holiday for the PS3, with a Slim + Price cut, and there's not much competition in the same genre, so it'll have a strong opening week, a strong holiday, and go on to sell 3.5-4 million units.
