All right...my picks, based on whatever matches I can remember off the top of my head:
HBK v. Cena
~~I agree with Nekkid. I think a loss in this 'mania appearance would probably hurt Cena. Cena will win most likely win, or it'll be a surpisingly close match that Shawn'll sneak in a win at.
Undertaker v. Batista
~~Taker. I know, a lot of people are claiming Batista to win and 'Taker to retire, but I'm saying win or lose, Taker's pretty much done by year's end anyhow.
MVP v. Benoit
~~Benoit. Just because MVP annoys me and sucks that badly.
ECW Originals v. New Breed
~~Ya know, the New Breed/Blood shtick was lame when WCW did it, and it's even worse now because the best in-ring guy the New Breed has is Matt Stryker, and he's not even that good. A lot of the Originals are on their last run, though, and that, more than anything, gives them the win here. Send the guys that made the brand/company famous out on a high note.
Money in the Bank
~~I'd love for Punk to win this, but I don't think he will. I'm gonna go with Orton or Kennedy here. Long as it ain't King Booker, I'll be happy. That gimmick blows.
Umaga v. Lashley
~~The battle of awful main eventers. Neither of these guys is really worth the effort, imo, but since Lashley's credibility seems to be slipping faster than Umaga's, I'll go Lashley.
Meleena v. Ashley
~~*shrugs* We all win on this one.
...I'm forgetting one...oh!
Kane v. Khali
~~I hope its Kane, but considering his colossal, Big Show-esque losing streak at 'Mania, I'm pretty sure it'll be Khali. Cuz, you know, we just need that other main even star that has no talent while guys like Benoit & Shelton Benjamin go nowhere.
