MTV Games boss Scott Guthrie has indicated that he expects Green Day: Rock Band to sell more than The Beatles: Rock Band.
While the Fab Four's videogame debut last year was critically acclaimed - Eurogamer's resident Beatlemaniac Johnny Minkley awarded it 9/10 - sales worldwide were reportedly well below two million.
That's more than Guitar Hero 5, also released late last year, but far fewer than Rock Band 2 or Guitar Hero: World Tour 12 months ealrier.
"We were pleased with the performance of Beatles: Rock Band but we were expecting higher sales," Guthrie told MCV.
"Our core audience of 16 to 34-year-old males are much more familiar with Green Day music than The Beatles."
"Green Day probably has a much higher awareness than perhaps The Beatles did."
Green Day: Rock Band is due out for PS3, Wii and Xbox 360 on 8th June.
