That's the same thing I heard!! I believe it 100%!!
Disney owns the rights of Hanna Montana and the Jonas Brothers, thus probably won't have to pay them the royalties they pay Aerosmith (I don't know all of these details) but it would make the attraction more Disney-like...and many young girls will be thrilled. I love RRC, don't get me wrong, and I love Aerosmith, but we are coming into a new age. These young kids are into different things and Disney is all about keeping up to date and thinking of their audience. I bet the attraction will be an instant hit for teens/tweens and their parents. Older guests will be disappointed I would guess.
