I simply said HBK because some people have mentioned him having something to do with those videos as well, although I find it highly unlikely.
Imagine the pop if Orton comes out, no Cena, the lights go down and then one of those videos starts to play, then out comes Jericho to fight for, and win, the WWE title. That would be the best moment in wrestling in years.
Although it's not likely, so meh.
