I honestly don't see Hunter winning this thing, nor can I picture WWE (of all companies) to make Rey Mysterio the main man with the spotlight on him leadinh up to and including WrestleMania. Which basically means that the only other option is Orton. From my understanding WWE management feels quite bad about pushing RKO to World Title status too soon, and then dropping the ball once he got there. A rumble win and a Mania World Title win might be what he needs to start solidifying himself as the bonified poster boy of WWE that he will eventually become. (oddly enough I suggested that he win the title at Mania 22...before he won the title for the first time
)
That having been said...if Benoit wins, and then faces Angle at the Main Event of WrestleMania...I swear to speak only kind words about WWE from that point forward.
