I'll be so bold as to predict now, bookmark this thread, and not make a single edit till after January 29th.
Winner: Anyone's ball game really, but I see Randy Orton Most eliminations: Kane will break his record of 11 this year. Iron Man: Dolph Ziggler followed by Alberto Del Rio Shortest lasting: Santino Marella will break his record of 1 second by not even making it into the ring. No. 1 and No. 2: Zack Ryder and Dolph Ziggler Surprise entrants: Jericho and Skip Sheffield Challengers for WWE/World Championships: Mark Henry and The Big Show - John Cena
I could see Barrett coming out number 1 though and looking all smug only for "I HEAR VOICES IN MY HEAD" to hit and Orton to be number 2.
