I'm actually looking forward to Payback.
Wyatt/Cena in a LMS match: Cena works so well in that environment. And it becomes that much bigger if an opponent can put him down that hard. The only thing comparable with Cena is an "I Quit" match, but he's never lost one of those and it's not time for him to do so. Evolution/Shield II (or 3 or 4 or whatever...doesn't matter): these guys have proved they'll go all-out for a PPV match and it will be amazing to watch. I'm pretty sure Batista gets "injured" or something at Payback to let him go do movie promotion. Perhaps that leads to a new Evolution member or it leads to Evolution's second run ending, either of which can be good for business.
RVD/BNB should be an excellent match. They both know how to work (more Barrett now than RVD) and I think Barrett knows how to get a good show out of Van Dam. Usos/Wyatt Family for the Tag Titles should be a fun match. I expect the Wyatts to win if this is the case. Sheamus/Cesaro has a great deal of potential and would allow them both to show what they're capable of. Rose/Swagger (another one I'm pretty sure will happen) will be interesting. And we'll finally get to watch Adam Rose wrestle a match on the main roster (no bonus points if he has a "warm up" match prior to Payback).
