What if they're delaying to coincide with the debut of original content on the WiiWare channel, and it will be the first game to use the WiiWare channel to update the game, AND it will launch with the expandable hardrive (20GB disk with an SDHC port ftw!!) which would further it's status as the Wii's first "complete" game, thus far they've thought of everything for this game, this wouldn't even be the icing on the cake, it would be more like the bride and groom figurines on the top...
Of course, it's never going to happen.
