WWE have planned to replace their annual Elimination Chamber event in February with a more quality and less of a non-gimmick Pay-per-view show called WWE Fast Lane or Fast Track.
Wrestlezone has reported that World Wrestling Entertainment plan to shift the Elimination Chamber to June in place of WWE Payback. Normally, the summer events of WWE are the ones which perform well financially, and Elimination Chamber and Money in the Bank in July are two of the more popular events of the WWE calendar, which would lead to a 3-month gap between the good events, including SummerSlam.
Elimination chamber changed to accomodate Brock Lesnar
New Champs in WWE! More RIGHT HERE
The fact that WWE currently has adopted only one world championship is regarded as one of the major causes for the change in the PPV schedule. Brock Lesnar is the present reigning champion and he is not expected to have his title on the line between Royal Rumble in January and Wrestlemania 31 in April.
Elimination Chamber used to be the platform where the Rumble winner picked the world champion he wanted after the chamber matches concluded. In the past year, the world champion had to win the Chamber match to reach Wrestlemania. There is a popular belief that WWE wants to make changes in the schedule so that they can save Lesnar from getting injured before Wrestlemania 31.
WWE are yet to announce anything officially but considering the event is close, speculation is rife that something is sure to be declared soon.
