I'm sticking by that I want to see HBK/Taker 2. I LOVED the hype to this match last year, and I felt the match was possibly the best of the past few Manias.
The reason I wanna see HBK/Taker 2 is because HBK is such a ... dominant name/figure when it comes to Mania. He just seems like the most legit threat to Taker's streak. I haven't felt like 'wow, this guy could actually end the streak' since last year. And with the recent threats/comments from HBK of late, I'm feeling more and more that he could be the one, if anyone, to end it.
I think that feeling is something they can't do with Cena or Jericho. Those guys are good, but there's just no chance they'll end the streak. They need the HBK-like guy. They need that guy who's been here for years, who's done everything, who's most 'dangerous' at Mania to make it a legit threat.
Kane? Lol! What a pointless opponent to have end Takers streak/Mania career. The WMXX match sucked shit, and since then Kane's done nothing really to earn another shot at him. So what if they're character-bros. I think this is possibly the worst choice for Taker.
