AiC had Rockfest in the tour dates that were originally released. I doubt that Rockfest has bands like Ghost, The Sword, Smashing Pumpkins, etc. Since its a one day fest.
As far as ROTR goes, this is a pretty solid lineup. The headliners are great, and I like some of the other bands as well. People are always bitching about the lineup because for some reason they always want the same bands. No A7X, Slipknot, and Disturbed are not playing every single year. Get over it.
