I have no idea. But its possible WW since its launching in its big markets early, combined with the price cut. If its marketed right with the Slim id say its possible.
If it can do 800k WW week one, which i believe is entirely possible, combined with the average drop to 300k week,
Uncharted 1 sold about 130k per week for the first 5 or 6 weeks WW. New IP, expensive PS3, with its staggered launch.
So the hype its buliding this early it very well could because of the slim and vast improvements made to the original.
It wasnt bundle until late and if you look at the Others numbers, the game was a huge hit right away. Now with the built up install base and ever growing on others this game could clear 1 million alone in Others by the first week of december.
