At WWE Money In The Bank, a vignette aired and it was produced in a way that leads fans to believe that Bray Wyatt is returning to the company.
Wyatt's return is not confirmed but he has been dropping hints as of late and he recently trademarked the "Wyatt 6" name. He has also made it clear that he plans on wrestling again and that he is healthy.
Another possibility is that this is a tease for Gable Steveson because there was a gold medal shown during the vignette.
Steveson appeared at WrestleMania but he hasn't been seen since that show. The company has high hopes for him and many have compared him to a young Brock Lesnar and Kurt Angle.
