Uncharted 2 has outsold Killzone 2

[GreyianStorm]

Uncharted 2: Among Thieves sold ~190k copies last week, bringing it's total to 2.31 million. This is approximately 150,000 greater than the number of copies of Killzone 2 sold to date. In just 10 weeks, Uncharted 2 has outsold Killzone 2. Just how far could Uncharted 2 go? It's almost guaranteed to break 2.6 million by year end (unless the post-Xmas week sees a massive decline in sales).
