It looks like there are preliminary plans to resurrect the WWE No Way Out pay-per-view.
The newly-designed WWE website lists No Way Out under "shows" after Money in the Bank but before SummerSlam. This would make it WWE's July pay-per-view that was listed as "to be determined."
At this point nothing is confirmed but you can view the listing for yourself at the newly-designed dot com.
No Way Out in February 1999 and 200-2009 but was replaced in 2010 by Elimination Chamber.
