Um yeah... didn't someone state awhile back that elites account for like 15% of XBox sales? And that what the reason they bundled Halo 3 and Fable with Elites from now on? MS still wants to make a profit off *something* so they make profits off Elites.
I would say they easily profit off pros now to.
Arcades? Who knows. But I'm sure Arcades still make up a bulk of the sales right now.
It's just that simple.
