GoNintendo has culled a rumor from the May issue of Game Informer that may mark a major shift in Rock Band song possibilities. According to the "Loose Talk" gossip section of the magazine, The Beatles: Rock Band will allow multiple singers on songs, in order to better replicate the harmonies brought forth by the Fab Four. The rumor bit also mentions the possibility of user-created downloads in future Rock Band titles.
On the confirmed front, Kotaku debuted the box art for the standalone and bundled versions of The Beatles: Rock Band. You can get a nice look at a pastiche of all the covers on Kotaku, or hit up the Amazon pages for each version to get a higher resolution image of each game separately.
The Beatles: Rock Band will release on September 9th on the Wii, Xbox 360 and PlayStation 3.
