Wreslemania 26 Location/ What I think should happen at Wreslemania 24

The location of Wrestlemania 26 is the same place where the Superbowl is being held, The Arizona Cardinal's Stadium(or whatever it's called)

I think that at Wrestlemania 24, The WWE Title match should be Randy Orton vs. Jeff Hardy vs. Triple H vs. Either John Cena or Umaga. The reason I mention John Cena is because there is talk that he may return at Wrestlemania 24. I doubt this will happen but hey, it could.
