There are some highly realistic Royal Rumble winners that have already been posted; HHH, Cena, Orton and even some much needed pushes of younger talents; Del Rio, Morrison, Barrett and Sheamus (none of who I think are ready to main event Mania). I also would love for Punk to win the Rumble in a awesome comeback, but I am realistic, I dont see it happening.
I really would love it if Jericho won it, I know that the suprise entrant to win concept has been done to death, but like previously stated, he was starting to get a modest (but growing) face reaction before he left. I feel that having him make a suprise return not necessarily at the Rumble itself but perhaps at TLC or a few weeks before the Rumble to build up his entrance in the match and potential win could do a lot to set up a possible Jericho/Miz or Jericho/Orton encounter at Mania
