Then again, there wasn't even the slightest hint of effort put toward the Wii. Guitar Hero will continue to dominate on that front if nothing else, especially with confirmed DLC coming with World Tour. That is, of course, after Harmonix claimed it was technically impossible... y'know, just like including the character creator was technologically impossible (something else World Tour will have).
Harmonix has already announced that RB2 for the Wii will have DLC and online play. There's no word yet on whether the character creator will make it to RB2 Wii yet but it definitely won't be as gimped as RB1 in terms of features.
