actually I was at that show too... I was sitting in the 2nd row from ringside nearest the entrance ramp.
I loved that fat guy on the other side of the ring that was taunting everyone and got the Hurricane mask. That was funny.
but with the pyro and presentation thing, I think it's pretty rare when WWE goes all out like that on normal US house shows. I can understand when they go to Europe and other places around the globe, but in normal US House shows I think they just use the bare minimum.
Also... those were WWE speakers, not the stadium's speakers. I've been to several concerts there, along with a bunch of High School hockey toruneys and the sound was really good. You can blame the sound on the 4 dinky speakers that were above the ring.
