As I have said before I am not very good with the software numbers, but I will say I hope both games sell extremely well since they are both awesome games (I say this with personal experience, buahaha).
Anyways, if I have to take I guess (and for me its strictly a guess) I will go with:
Bioshock: 320k
Metroud Prime 3: 350k
The only reason I give metroid the edge here is because Bioshock has a PC version and Metroid is an established well known franchise being released on a console where there haven't been a lot of hardcore love over the past 2-3 months. All in all I have no idea on the exact numbers but I am guessing MP3 will have a slight edge. Regardless both games are must owns for anyone with the appropriate platforms to play them.
