Triple H indeed definitely does need to stay away from competing in the main event for a world championship. Edge, Orton, HBK, Punk, Jericho, and Batista should be the potential replacements for Triple H. All though I'd much rather prefer to see somebody new win it this time but that won't happen.
It's funny people from the WWE criticized WCW for not pushing new guys when the WWE has been doing the same for a while now. Sure Sheamus, Drew McIntyre, and Christian are doing pretty well but how about all those other talented guys? Yep they are jobbers.
