I want the Triple H vs. Sheamus thing to spill over to the R2W next year... leave that one alone for a while. PPV coming up allows for us to see an attack on Kane - he could tell Kane to quit meddling, it's not his problem.
It would fit because Sheamus is claiming it's his ring recently... everyone knows it's Taker's yard. Sheamus needs that huge Superstar push, something to really make him a top heel... the feud with Cena kinda jump started it, the attacks on Triple H kinda turned it over... if he were the one attacking Kane, it would start that engine up and he'd coast onto an incredibly successful career.
MVP CAN use the push (then again, so CAN everyone), but he's getting older, he's not really someone who capitalized on the opportunities he was given, I wouldn't dare give him the biggest storyline we've seen since Vince's death.
The only other person I'd love to see as the attacker aside from Sheamus, is someone who needs that jumpstart with his new gimmick, and that someone, is Ted DiBiase. Think about it, 20 years ago, his father brought The Undertaker into the WWE... and he's had a few storylines with the Undertaker (remember Taker vs Taker?). Everyone has said if Ted ever wants to go over, he needs to do it against Taker, and I think the WWE might be listening. You build up to Survivor Series, give Taker his time off over the summer during real estate... let him get over any bumps and bruises, have Ted paying people off... maybe to take the fall for him/build up his own little faction... then have him reveal it sometime along the way and feud with Kane/take him out.
Then at Survivor Series, have Taker come back and begin his ongoing feud with Ted which could hopefully carry over to WrestleMania.......
....then again, wishful thinking, I believe they call it.
