If this was the first in the series on the 360 then yes, it would move a good bit of hardware. Being a sequel of a franchise already on the system will not move many systems. If they bundled it with the first one (and charged a few bucks extra or whatever) then I could see this happening.
Ill be enjoying it on my PC (and cursing NO REAL CONTROLLER SUPPORT!) Would be great playing this with my ps3 controller on my pc :)
