I wouldn't be surprised at an RVD turn also, but if it happens I don't think it'll be for a while.
I could see Paul Heyman getting more and more powerful, with more and more guys (mainly former ECW stars) to join him. He trades wins and loses with Eddie as they are doing now, and this lasts over the entire Summer, leading up to Summerslam. Either before this show, or right after it, RVD finally turns on Eddie and their feud begins (either to begin or end at Summerslam). In the end, I think it would be insanely cool to have their big title match end up being some sort of gimmick, like a simple cage match or a simple No DQ match. In the match, when it looks like Eddie is about to sneak his way to victory once again, Heyman has all of his boys (a pretty large group by this point) run in and help RVD just dismantle Eddie. Sure Eddie has a bit of help, but it's no use as Heyman's group is much too strong at this time.
So yeah, RVD ends up destroying Eddie with help, and becomes the new WWE Champion. Then, the following week, Heyman, RVD, and everyone else stands in the ring at the start of the show and announce that they are all leaving the cesspool that is WWE, they are taking the world title, and are restarting ECW once and for all.
Sure it sounds a bit like the nWo and how ECW first started up, but it's on purpose. It's worked before and it could work like a charm once again. Hey, I know I'd love it.
I love to dream.
