Kennedy's wrestling Batista in a singles match, so he's not in. I doubt either Hardy or Nitro will be in for a long time, MNM are wrestling the Hardys in another match.
I think HBK will win (just looks like the way they are heading, HBK v Cena, somewhat), and besides Punk and Carlito, he would be the one I would want to win as well.
