I think those games are more likely just going to influence Capcom's decision when handing out developement to western studio's, they've been stung twice by it now. Dead Rising 2 seems to be coming along fine though - they just need to partner with more capable studio's.
After Tatsunoku vs Capcom's NPD's figures I'm iffy as to what Capcom have that could sell big numbers on the Wii - except if they made a full blown RE, but they're probably better suited to putting any project like that as a HD multiplat.
Maybe they could ressurect the Megaman Soccer series and have Mario and Megaman and the FIFA world Cup 2010 :D. Guarenteed 10 million seller.
