"We want to apologize for the delay in getting RB2 onto the Wii and to reaffirm that we believe that Wii is an amazing and unique fit for Rock Band 2, and one that we care deeply about getting right," the company stated in an official statement. Going forward, Harmonix hopes to release games simultaneously on the Wii and other platforms. The PS2 and Wii editions of Rock Band 2 were co-developed by Pi Studios.

Unlike the belated Wii release of the first Rock Band, the Wii edition of Rock Band 2 is fully-functional compared to its Xbox 360 and PlayStation 3 brethren. It's got online play, support for downloadable content, world tour mode, and even character customization. Downloadable content can be run off an SD card or the Wii's internal memory.
