1. Sucks, hate it, just hate it. What they should do is have Batista win beat the clock (No, I don't know who's in the competition, I'm just saying), then lose the championship at Royal Rumble. Knowing that a Smackdown superstar has won the Royal Rumble 4 years in a row, it's probably not going to happen again, so at No Way Out, Edge loses to Rey. Weeks later on Smackdown, in a tag team match, Taker & Edge beat Batista & Rey, meaning Taker will face Rey at Wrestlemania (like you said, but here's the twist). After Taker quickly, QUICKLY (like, in 5 minutes quickly) wins the match, Edge uses his rematch thing to face Taker directly after the match, in a ladder match. Before the match starts, Rey uses a microphone tosay "You wanna do this, well then make it triple threat", After a chokeslam off the ladder by Taker to Mysterio, Edge spears Taker off the top of the ladder, then climbs up, yet Taker still doesn't give up, shaking the ladder til Edge falls of, and then grabs the title.
2. It would be nice, but probably not gonna happen. Shawn Michaels would counter a Swanton BOmb, super kick Hardy, and win.
3. Easily Triple H
