I'm not sure I've heard anyone say that we're pleased with [zack & Wiki's] sales and alas, I can't really comment on the prospects of a sequel. I think there was a lot learned from the title though. - Christian Svensson, VP, Capcom
Not long ago Capcom was looking for ways to change the game in order to make it more sellable, but slowly the prospects of a sequel have gone down the toilet if comments from Capcom are to be believed. The really sad part of the above quote is the so called lessons learned. As far as I'm concerned Capcom hasn't learned that they need to advertise their Wii games if they want them to sell well, but they haven't shown a real understanding of the Wii or it's audience so that's to be expected.
