The game is set for an exclusive early launch on Xbox 360 this September with instruments sold individually, while the 'Special Edition' bundle a month later say retailers.
What's got the fans ire is the cost. Getting a hold of the bundle saves about $50 instead of buying the peripherals and game separately. No official statement yet.
The official Rock Band store and Game Stop both cite the bundle to be arriving October 19, the same time as the rest of the platforms - PS2, PS3 and Wii.
"Releasing Rock Band 2 as a standalone disc on September 14th and releasing the Special Edition on October 19th strikes me as pretty messed up," says one fan, robpe36, over at the .
Another fan, Pandemonium, posts: "People who were on the fence about whether they should buy the bundle and upgrade their controllers or just buy the game are now less likely to buy the bundle, since they have one more reason not to (they'd have to wait an extra month). I think they are going to lose money."
