Kinda off topic since y'all basically covered everything, but don't rule out Triple H in all of this.
The Game wants his guaranteed rematch with Roman Reigns for sure, that's his character. He wants Roman, but if he's gunning after title that can piss off Seth who Stephanie has already told he's on his own now... Some form of a reunited Authority in the way of the rematch - or even showing up at MITB, will leave the question if anyone's on anyone's side...
And of course if you really want to run with "Who's the Corporate Champ" crap again, may as well do it with the actual corporate champ, right?
