OkBackwards compatibility with Rock Band downloadable music content. All previously purchased tracks will immediately load into your Rock Band 2 song list. No need to re-purchase or re-download The biggest and most diverse soundtrack ever featuring some of rockâs most prolific acts, comprised entirely of master recordings Major new and dynamic online modes that will connect the entire Rock Band community in more ways than ever before both locally and globally More variety of instrument choices than ever before with new and improved drum and guitar peripherals, enhanced functionality and innovative new designs - all fully compatible with the original Rock Band instruments Some of the features by the way I found this at ign.com
Nah, it will be a huge bust. Guitar Hero 4 is going to be the same as Rockband, but better. GH4 will have drums, bass, vocal and guitar. Rockband's guitar is a joke compared to GH's guitar. So in my opinion, GH4 will be awesome, but Rockband 2 will fail.
