3.5 million xbox360
2.5 million ps3

3-4 mil overall

I predict this game will be as close to a first person shooter without being a first person shooter as a game can be. On that basis I predict it will sell at least 7 million on PS360 combined as the HD crowd sure do love their shooters especially the 360 owners

I expect it may struggle. From what I've seen/heard it looks like they've lost much of the atmosphere from previous RE games and made it a generic 3rd person shooter. Not good on systems that specialize in shooters. Will sell okay but not great.

I predict this will be the best selling RE game ever. It is going to be better than any previous iterations and sales number will prove that!

1,7m X360
2,3m PS3
~0,5 other

and 1,5m Wii

I'm gonna say....

3.5 million for X360 - Mostly in NA
2.0 million for PS3 - Mostly in Japan

5 million between the 360 and PS3...we all know the 360 will get the bigger opening, but the ps3 version legs will put this about 2.8 to 2.2 in favour of the 360

resident evil 4 did 2 million on ps2 according to capcoms press release (it is hugely over tracked here)
1.4 million on the wii (so far)
and 1.6 million on the gamecube, so about 5 million plus assorted pc sales
according to http://ir.capcom.co.jp/english/data/million.html
so I think it will probably perform in a similar manner, maybe 2.5 million on 360 and 1.5 million on ps3 so I think 4 million lifetime,

2 million X360
2 million PS3
