WoW can't wait for August with the release of the 4GB Xbox 360 Slim. I think almost all of the 360 sales were 250 GB slims and a few 'old' elites. You can't find a $199 Xbox 360 these days (just checked bestbuy and amazon). The 4GB SKU will change that and it might bump sales.
Madden will sell quite well, too.
September is Halo Reach time, with a special edition console. Sales will increase due to holiday boost as well.
October is Fable III time. It won't move much hardware, but sell a nice amount of software.
November is Kinect and CoD Black Ops time. Huge hardware and software boost incoming.
December will see great sales anyway.
Early 2011 we will see Gears of War 3, Crysis 2, Bulletstorm and Rage to keep sales on a high level.
Imagine not having GamePass on your console...
