WWE Elimination Chamber is live on pay-per-view this Sunday from the Bradley Center in Milwaukee, Wisconsin.
The Elimination Chamber PPV started in 2010 and has yielded three world title changes, all in 2010. No world title changes occurred last year.
In the history of the Elimination Chamber match, there have been seven world title changes. It's an unpredictable match that has the ability to significantly shake things up heading to WrestleMania.
The event will feature an Elimination Chamber for Raw and one for Smackdown.
Raw's Chamber match features CM Punk defending his WWE Championship against Chris Jericho, The Miz, Kofi Kingston, Dolph Ziggler and R-Truth.
Smackdown's side has Daniel Bryan putting World Heavyweight Championship on the line against the Big Show, The Great Khali, Cody Rhodes, Wade Barret and *SPOILER* Santino Marella.
Other announced matches include John Cena taking on Kane in an ambulance match and Tamina Snuka challenging Beth Phoenix for the Divas Championship.
This is the second WWE PPV in a row to have only four matches booked heading into the card. I have hopes that the Raw elimination chamber can carry the event.
