What if they had a huge retirement match? A four way match with Austin, Rock, Michaels and Undertaker. I really think it could work, just have them all go out for one last time. Rock has stated that there is nothing left for him to do, Michaels should be retired anyways, Austin is pretty much retired now and Taker could finish off his Wrestlemania streak. I would love to see this match, toss in an "enforcer" at the entrace so there will be no run-ins and just let these guys go at it.
