I don't think HBK will win, he is going for a break after WM so there is no point for him to win IMO. It would have been better if no one knew HBK was going for a break after WM because then no one would have any idea who would win but if HBK wins, it would be a waste because there would be no pissed off Undertaker coming after him for breaking his streak.

Although this is WWE and they do weird things sometimes, so it is possible for HBK to win, it would not be logical but who says WWE is logical lol Atleast we now know the HBK vs Taker match will be the last match now, so it should be an awesome ending for the show
