I'm most excited about seeing Ultimate Warrior - really hope he makes an appearance in one of the matches (perhaps the Battle Royal).
As for the actual matches - i'm not overly excited about any of them. Undertaker has been my favourite for years, but he's old and unfit, and can barely hold a match together any more. My predictions as follows:
The Usos (Jimmy and Jey Uso) (c) vs. Los Matadores (Diego and Fernando) vs. The Real Americans (Cesaro and Jack Swagger) vs. Ryback and Curtis Axel
Daniel Bryan vs. Triple H
The Undertaker vs. Brock Lesnar
John Cena vs. Bray Wyatt
The Shield (Dean Ambrose, Seth Rollins and Roman Reigns) vs. Kane and The New Age Outlaws (Road Dogg and Billy Gunn)
André the Giant Memorial Battle Royal - think only 27 participants have been announced so far. Of them, I pick Big Show. However, I fear Hulk Hogan may well end up winning it somehow
Vickie Guerrero Divas Championship Invitational Couldn't care less. AJ is pretty - if she's in it, I want her to win
Randy Orton (c) vs. Batista vs winner of Bryan v Triple H
