I really like his idea, though like he said it probably should have been started a couple of years back if they were going to go in that direction. The question does still remain though, who should break it, and I disagree with Lance's view that it doesn't matter.
I don't think Cena would make any sense, really. The Rock did the whole passing of the torch thing only recently, and he's as over as he's ever going to get. A face CM Punk maybe, but even then I'm not really sure.
