Lambast me if you will, but any kind of sequel or upgrade for Wii Music would have me frothing with excitement. I'm glad to hear it had good overall sales world-wide. The kind of critical panning it received from most western sites/magazines made you think the game deserved a condemnation from the pope. But then I picked it up, almost out of morbid curiosity, and wham--I loved it. (Not to mention it includes WHAM's hit single... I'm telling you, an electronic slow jam version of "Wake Me Up Before You Go-Go," full of hand-claps and space drums, is a thing of beauty.)
Anyway, I really hope this wasn't some kind of translator error, and Miyamoto and the gang actually do release some kind of iteration or update. Or at least a new Channel with some kind of patch, allowing better sharing capabilities and new songs, would be groovy, too.
