1)will we ever see the trio ( big show, Paul heyman and RVD ) in an ECW ring again in the near future??
No, Big Show has about a 10% chance of returning. Paul Heyman has about 25% chance, RVD has about 40%. So i think we would be lucky to get one, although you never know. I think ECW will likely bring in some new talent, so they won't have to use jobbers every week.
2)JR wrote in his blog that HBK vs ROCK has never happened..will it be a good idea if WWE makes that match at WM 24 next year??
You just can't "make" matches. Yes, it never happened, and yes it would be a great match, but i can't see it happening. I think there might be a little backstage heat between HBK and Rock too, not certain on that though. Because i believed they puposed the match a while back, and Rock didnt want any part of it, and that made HBK mad. It doesn't look the rock is returning, as he has talked bad about pro wrestling, but never say never, like i said before. If a few movies flop, it could return for a few months. I guess if i could pick one dream match for the rock if he were to return, it would be against John Cena. I'd probably hold off on that till wm25 though.
