It will most likely sell about 60-65% on the 360.
Initial pre-order data had ME2 at 500k. I'd expect NA to wind up with ~750-800k for first week. PAL should add about half of that, so approximately 1.1-1.2 million sold on the 360.
I'm unsure how it sold on PC. Dragon Age outsold Mass Effect on Steam, so I don't know if that's a good thing or a bad thing.
Back from the dead, I'm afraid.
