Unless Taker fights Sting, and even if he does, he shouldn't be the final match over Cena v Rock. WWE should have learned their lesson at WrestleMania 18 with the Hogan/Rock match. It was the main event, no matter if it was the first or last match on the card, and putting on Jericho v HHH after it was a mistake, even to Jericho, who was in the match. I don't see the logic of doing it, otherwise.
No matter who Undertaker faces, though it should be exciting, it won't trump the other match in hype. I mean, it would probably be best to go on third to last, because: 1) we all know what's going to happen; 2) if it's just him vs HHH again, then that's not a main event match. I agree that Taker deserves such an honor, but it's just not the situation.
Finally, if we know that Punk is going to be in the title match (and I swear if ADR is anywhere near that match...), he'll probably be the sub-main event, just because they really do seem to value him as a future mega-star. You could probably expect someone like Miz, who's another future face of the company, to be his opponent. I'd expect the WWE to put this right below the Rock and Cena because it's a great way to promote them as future stars. Taker won't be any higher than third to last, I wouldn't imagine, but he shouldn't be higher than the sub-main; that's Rock and Cena's spot.
