Uncharted 2 will be well into profit and of course Uncharted 1 would have done very well for ND too. Even allowing for the larger games library and fairly rapid stream of titles now, looking at how much Uncharted 2 is outperforming Uncharted unless it dies overnight its final LTD should be very nice. Plus given most people/reviewers found Uncharted 2 better than the first it's pretty much a sure thing number 3 will do very well, too.
Also, with ND status they will have got a nice share of the pie as others have pointed out.
Oh, and a chart, because I've noticed no one seems to use them anymore!
