What do I think will happen? I think Roman will retain. What do I want to happen, I want Cena to win it and become the 17 time World Champion and if he has to screw off immediately, have Big E cash in and win it off him. I mean, you could just have Big E cash in on a victorious Roman but if you're going to put the title on Big E at SummerSlam, might as well break history while you have it, even if it's only in WWE interpretation of history with Flair's unrecognized reigns. Plus like, if Cena wins this one they can set up for a rubber match with him & Reigns, and they're kind of thin on like viable blockbuster matches for Cena.
I'm not watching so it doesn't really matter to me but I do hope this match is at least better than that god awful match they had at No Mercy years ago.
