There seems to be a fundamental problem with the thinking behind the posts on this thread. Porting a game from 360 to PS3 or vise versa isn't going to make it just as financially viable to publishers as doing Wii exclusives. Why?
A) Games for 360/PS3 demand the highest graphical resolution to be competitive. For the Wii great graphics do not equate to better sells. So while I truly do want to see some graphically outstanding games on the Wii, most games will go with simplier graphics (EA Playground/Boogie) and thus be even more cost effective. Innovative fun sells on the Wii, not graphics and fun is a whole lot cheaper to produce.
B) At current sales rates the Wii will surpass the COMBINED total of 360/PS3 sometime next year. That makes getting 300k on Wii easier than 700k on 360/PS3. (yes, I know, price cuts and AAA games will dramatically increase 360/ps3 sales by this holiday season - I'll believe it when I see it, and even then it'll only delay when Wii will surpass their combined total)
C) In case your game bombs, it's a lot easier to take if it's a Wii game than a 360/PS3 game.
D) Publishers can expand their base on the Wii (look at EA Sports' Family Play feature), to capture all new customers. With the 360/PS3 it's limited to the same core gamer crowd that's been in steady decline for years.
The good news is that games made for the core gamers will continue to sell better on the 360/PS3 and for publishers who want to make those games, they'll continue to do so profitably. But expect EA/Ubisoft/ other large publishers and ALL Japanese publishers to increasingly support Wii over 360/PS3 in the next couple years.
