Xbox 360 owners have been playing Rock Band 2 for about a month now, and today MTV Games and Harmonix are finally officially revealing the release dates (sort of) for other consoles.

PlayStation 3 owners can pick up the game this Sunday, October 19, and should blow up Harmonix's office phones to thank them for the short notice. The Wii and PlayStation 2 versions of the game will be available in December; no specific date has been revealed. 

Houston, TX-based Pi Studios has been revealed to be handling the Wii version of the title, which has been confirmed to support online modes and downloadable content. The game will feature a full online in-game Music Store, and will contain every piece of DLC currently available, dating back to the original Rock Band. 

Details on release dates and pricing can be found after the jump. 

[Update: Quick correction, straight from Harmonix -- the Wii Rock Band store will not feature a full DLC library day one, as we originally reported. It will, however, offer up 50 tracks -- 30 DLC, along with the promised 20 free tracks. Harmonix plans on updating the back catalog moving forward, and will be working to have the store up to date with other consoles in the coming months.]
