I think there is a lot of expectations that game like Kid Icarus, Zelda, Wii Sport Resorts or Punch Out will help Wii sales.
I have no doubt those games can move a lot of software but I would expect by now that most of the GC owners have already purchased a Wii and it's not games like those that made Wii the phenomenon it is now.
Wii sold like hotcakes because of brilliant marketing and because of games like Wii Sports, Wii Fit and Guitar Hero...
Satisfying the core gamers who may be unhappy with the latest release is good, but I doubt it will boost WIi hardware sales as some are expecting...
Basically people are applying the same concept they apply to HD consoles (core games will boost hardware sales) while the Wii has demosntrated that core games are not the reason why it has been selling so well so far.....
