Yeah, it will make for an interesting Raw that's for sure.
This, everyone will be keen to see who Nash is with:
1. Cena, who was scared HHH was going to rig the match against him, also, remember on Raw he told Punk that he needs to win it more than Cena does, maybe he hired Deisel to shut Punk up.
2. HHH, who just doesn't like Punk, wants to do what's good for business (give Del Rio the belt for the Mexico tour, fits in with the reality storyline)
3. Del Rio, paying him off as a bodyguard
4. Stephanie, flexing her muscle, she doesn't like Punk
5. Laranitis, again he doesn't like Punk at all
6. Vince, he blames Punk for losing his job, and wants to take him out and get it back again (I doubt this will happen though)
One thing all 5 have in common is none of them like Punk.
I think Steph will have some involvement in the whole thing (and become another key player in this storyline), as will HHH and Laranitis. Cena will stay in the title picture (triple threat at NOC against ADR and Punk) before getting out of it and moving onto the Rock. Del Rio will probably have a minor role, I doubt Nash is in cahoots with him, and was encouraged by who hired Nash to take the opportunity.
I think Punk will blame HHH for what happened, even though he will claim he had nothing to do with it. I think Punk will be champion again before the year is out (ADR will hold it for a few months max), and it will set up Punk vs HHH at Mania, with Laranitis, Nash and Steph to all be anti-Punk until one of them flips on the rest at Mania helping Punk win.
It was an underwhelming end to a fantastic PPV no doubt, but I won't write off the storyline yet, there's still potential there. Raw will be make or break for the storyline.
