The advantage for 360 on Rockband over Wii is due to timed exclusiveness.
The advantage it has gained over the PS2 overall is because the PS2 is a dieing platform
The advantage the X360 gets in general is because these games are very America-centric, where the X360 had the sales lead only 10 months ago, and the Wii is probably only recently catching up on the more accurate measure of "months of ownership" that The Source or DKII uses.
