i think that this game, and all the other core wii games from 2009 (madworld, overkill, conduit, metroid, dead space etc), are all just too late in the wii's life.
i think the core gamers who bought this type of game on the wii years ago, giving the 1.5 millions we see on re4 and cod: waw are now long gone to their ps3's and 360's, and there hasnt really been that blockbuster to tempt them off buying the latest release from the other consoles.
that and they likely traded in their wiis to get cash off a 360 :)
if the 2009/2010 schedule were all moved forward by a year becoming the 2008 and 2009 schedule, i think they would have sold more and more would have kept faith with wii core games, but the (relatively) barren years of 2008/Q1 2009 in terms of quantity of core games i think was a killer for the genre on the wii :(
Developers left it too late for these experiments and projects to work - they waited too long and their target audience was no longer there.
sad though. i preordered this and by a fair stretch it was my favourite gaming experience of this generation.
a truly magnificent title i thank EA for.
