I'm quite certain it will be on DVD after the show is finished touring.
I hope so but I'm not as sure.. I think it may be possible that they may feel that if they release a DVD of Immortal, than many may not feel the need to see MJOne in Vegas, even though it's a completely different show..
I have read somewhere on here that the Cirque president told a poster/user on this board (in person at an Immortal tour stop) that he was going to release a DVD of the show.. But I take that with a grain of salt..
