Goldberg isn't likely to be around WWE for much longer than WrestleMania, so WMXX will likely be his last WWE match. And, the cynic in me says that any World title match for WrestleMania pretty much has to involve Triple H in some way (probably with him going over yet again).
Also, I truly think that Undertaker will never lose at any WrestleMania to anyone. If he didn't lose to Triple H or Flair, he sure won't be booked to have the streak broken by Kane.
"When this bogus term alternative rock was being thrown at every '70s retro rehash folk group, we were challenging people to new sonic ideas. If some little snotty anarchist with an Apple Mac and an attitude thinks he invented dance music and the big rock group is coming into his territory, [that's] ridiculous." - Bono, 1997
THe WWF won't allow a recipe for freakin' WEED brownies in their cookbook! Jeez! What's he gonna print? "Okay, you start with an ounce of Cambodia Red..." Sure, I'd dig it, but the anti-WWF groups would shit their pants!
