Without knowing much about the new ownership I can't comment on what they might do. I think the Fertittas would have told him to pound sand, much like they did to M1Global.
Yeah, McG is the top draw and all that jazz, but he's not a commodity with long term drawing power. As in, chances are he won't be breaking records 15 years from now. Unless he's demanding profit sharing during his tenure ( which he already gets via ppv cuts) I don't see it as a good investment, rather opening the door to future stars making increasingly grander demands. It could be one of those ask for the moon, and hope for something realistic things though.
