My predictions:
Taker will beat Batista, for one last run with the belt. I'm confident about that, which makes me think Michaels will lose to Cena.
Michaels' reputation as a double-crosser has been brought up recently, and Cena seems wary of HBK stabbing him in the back - so I'd like to see Cena double-cross Michaels on the last RAW before WrestleMania. It'd be a nice twist, and make sense. Cena as a heel would be good, though they only just got the crowd behind him again.
Money in the Bank - Edge. He's got a WrestleMania streak going, so I think he might win it. I hope Kennedy does, since he'd have a chance of actually winning the belt.
Vince will lose, there's no way Trump would agree to get his head shaved. Plus, it wouldn't make sense for Austin to let Vince win.
I'm looking forward to 'Mania, though I'd like to see a match between two really good workers. Book Benoit vs. Regal and I'd be happy.
