The belief is that the new season will begin airing some time after WrestleMania 31. It's also believed that the show will be filmed in Florida at the WWE Performance Center.
Before Tough Enough plans were nixed last summer, the idea was to have all WWE developmental talents on the show but based on the issued this week, pro is not a requirement for the new season. It was noted that this season will have a different format than previous Tough Enough seasons. We do know that the new season will have some live elements to it.
There's also no word yet on who the Tough Enough coaches will be. Bill DeMott indicated on Twitter that he will be on the show but that's all we've heard. WWE had planned for Steve Austin to host the Tough Enough show they wanted to film in 2014 but his name has not been attached to this new season yet.
