Go on record: Bioshock and Metroid Prime 3 First Week Sales in the Americas

[joora]

I guess Bioshock will have stronger initial sales than MP3, mostly because large part of Xbox360 audience is FPS orientated. That said, i'm pretty sure that MP3 will win in the long run, as it will be a good reason for GC owners to switch to Wii, and make FPS lovers to buy Wii as the second console or PC-Wii combination (due to controls).

Also, MP3 will sell better than Bioshock(X360 ver) in Europe, because FPS players there are mostly PC orientated, so PC ver of Bioshock will be their first choice.
