THey need to have Batista win, then turn heel, Undertaker wins Rumble and Batista beats Benoit at Rumble, Taker/Batista at Mania with Taker getting one last title shot, win it, drop it to someone over summer 07, take a break, come back and feud with Edge (who will then be something like 8-0) and lose the streak to him at Mania 24 and retire.
