I think my assertions about Sports titles on the Wii are pretty much proven correct, after seeing how overtracked they've been here on VGC, relative to NPD this month, and heck, they looked bad even here. Nintendo even confirmed NPDs Madden Wii numbers with their own press release.
The Wii, clearly, does not appeal to people who purchase pro-sports league games. This is all but fact, from data a couple years running now. Even with "legs", its pro-sports sales are bad compared to its competitors, especially given the install base differences. Honestly, the "legs" (if you can call it that) of last years Madden on the Wii can probably be more attributed to the rapid growth of the install base, more than some sort of unexplainable appeal.
The sad part is that the first months numbers seem a lot worse this year, than last... kind of suggesting that more Wii growth is about the only thing that could save future Wii pro-sports titles from extinction in the near term. Its as if owners of last years Wii Madden actually chose to purchase the game on a different platform, or not at all, and it was mostly the new Wii owners who purchased this year's version.
IMO, that's just fine. There are a lot of other game genres for the Wii to succeed in (and it's doing just fine in other areas, it seems to me).
