So, it looks like they switch up their house show formats nightly. I just got an email for tomorrow night's show in Newark, as follows:
Cena & Mysterio vs Orton & Del Rio
Big Show vs Kane in a steel cage (w/Booker T as ref)
So they must do the match stipulations on a rotation basis. Cena you get the cage match one night, next night Kane you get the cage, Cesaro the next, etc.
That's kinda nice, it's like when your favorite band switches up their setlist every night...makes it interesting.
