I'm pretty sure that much like Goldberg showing up at last year's No Way Out, HBK will show up and derail Angle's plans, setting up both HBK/Angle and Cena/JBL for Mania.

Taker will likely get taken out of the equation by Heidenreich and/or Snitsky, setting that up.

I just caught the end of the Angle/Misterio match in Japan. Pretty good stuff.
