I like the idea of him cashing it in immediately after Edge gets the title back from Taker. It would make for a great run for both these guys over the next couple of years. Punk and Edge are part of the future of the business and Punk doing to Edge exactly what he did to Cena and Taker would only make it better.
If he goes to Raw and takes on Orton I doubt the E would allow Orton to lose to him. They are trying to build Orton up as the ultimate heel and losing to Punk (this early in Punks tenure in the E) would not look good for Orton.
Staying on ECW and challenging Kane or wasting the MITB on the ECW title would just be plain stupid on the E's part.
So Edge beats Taker/Punk beats Edge same night=pure win!
