This is what happens when you have masses of studios
We have already had 1 exclusive every month (if you count MS). They haven't sold that well but should all clear 2m, and we have SOCOM 4 and inFamous 2 to come soon
Then for the holiday we have Uncharted 3 and Resistance 3, both fairly good games I would say, and Uncharted at the least is a big hitter. People may be saying that M$ are keeping their big hitters up their sleeve, but all they have left are Halo from 343, Gears and Forza.
What will happen with 343 is unknown, but Uncharted and Gears are of a similar size, and Forza has been destroyed by GT though should still move some decent numbers
