Akuma-
Yes because if there was a Wii version it would make the game sell less total copies.. that makes sooooo much sense.
Wait... isn't COD5 going to be on the Wii? Woops there goes your sad theory about if it sells well on PS360 it won't be on Wii... COD4 was too far along by the time Activision realized what a monster the Wii was turning into. Oh, and PES- that sold pretty good on the 360 and PS3.. and looky here a PES:Wii. That is an amazing theory there buddy.
The only reason they would not port it to Wii is because they don't want to ruin the RE5 experiance on Wii(bad port or shoddy graphics).
Please tell me that if they had redone RE4 with better graphics(or whatever) it would have sold as well as it has on the Wii on the 360? or PS3?
RE has an audience on the Wii, it would not suprise me if they did something about it. Unless they hate money of course.
The PS3(and maybe 360, although they don't seem to be as bad) fanboys need to face the fact that "their" console of choice is not doing too hot, not terrible, just not great, and the Wii is doing awsome. Many of those franchises that you feel "belong" on your beloved console may just be multiplatform.... or you might not get them at all do to the extravagent dev cost.
