There are a few good options this year. Kofi Kingston, Ted DiBiase, Christian, and the Miz are probably four of the best choices. In fact, the crowd was going nuts when Christian nearly won last year; CM Punk actually got a fairly negative reaction when he beat out Christian at the last minute. I would also not mind somebody like Shelton Benjamin or Dolph Ziggler winning, and a rejuvenated push coming from that. Benjamin in particular has recently become a more well-rounded wrestlers, and he could use some Raw/Smackdown exposure in order to put that over.
As for John Morrison still being mentioned, I'm slightly surprised. Despite the IWC's hard-on for the guy, he really seems to have checked out recently, drawing parallels to Carlito in 2006. Perhaps a heel turn would be good for him, or else a program against somebody like Finlay or Regal, who will beat some good into him. For now though, he's lost his chance at being MITB winner. Maybe three months ago I would have been for it, but he's been very very average lately.
But, yeah. A line-up of Kofi Kingston vs Ted DiBiase vs The Miz vs Christian vs Shelton Benjamin vs Dolphin Ziggler would be a lot of fun.
