As noted a couple of days ago, WWE has made some changes to the Elimination Chamber structure. Fans have begun filing into the Talking Stick Resort Arena in Phoenix and photos have begun popping up of the new structure.
The structure changes were likely made to make it easier to suspend over the ring. The main issue with the previous structure was that it was tougher to suspend over the ring in arenas that have large scoreboards.
