The following comes from WWE.com: "Monday Night Raw’s abrupt conclusion last night was not due to technical difficulties. The decision to suddenly end the broadcast in that manner was made by WWE Chairman and CEO Vince McMahon, who gave this quote to WWE.com: “CM Punk was suspended indefinitely for his unprofessional conduct as soon as Raw went off the air.” With his WWE contract expiring on July 17, one can only assume that this suspension effectively terminates CM Punk’s tenure with WWE."

I'm pretty sure this is all part of the storyline. Regardless though, Punk was brilliant last night. That was one of the best promos that I've ever seen, and he deserves some mad props for it. Seeing brilliance like that also reminds me how much it's going to suck when he leaves.
If he leaves, the WWE will have monumentally dropped the ball. They could totally turn this into a long program, and make everyone some money. If they're letting him go, they wouldn't have given him the mic. He would've simply disappeared into the abyss.
Well, I think they're doing a great job with the storyline they have right now, because what he's been given reign to do over the last couple weeks has been phenomenal. I'd love if he only storyline left for a few weeks and eventually came back with the title, but I haven't heard anything about him signing any new contract extension with the company.
