None of these names strikes me as particularly interesting or creative. "Champions" is stupid, although i could see how Uprising could work.
It'd help if they gave us a brief on the nature of the PPV they are thinking of. Like, when they were naming Bragging Rights they sent out a survey of potential names, described the PPV something along the lines of "a brand vs brand themed event" (Bragging Rights won, obviously). It would help put all these names into context and would change my opinion on them.
Whatever they go with, i hope it replaces Hell In A Cell. Love the match, but a horrible concept to build a PPV around.
