Stone cold went on his podcast yesterday and addressed some of these rumours for his listeners.
He mentions that there was no deal in place or offered for him to be at WrestleMania 31, it just didn't happen.
He mentions that he is not going to be the host again of the Tough Enough series because it conflicts with his show Broken Skull Ranch. If they taped earlier he would have been able to do it but there is nothing he can do.
He finally mentions that him and the WWE could not come to terms with a deal after the first 2 podcasts' aired. He claims there is not heat between him and the WWE.
It just seems like there is more to this story that Stone Cold is not telling us. I find it hard to believe that they could not come to terms with a deal when the show was taping in his backyard of Texas. Maybe this is all a part of a story line to make viewers feel that there is no way that Stone Cold returns at WrestleMania next year.... Let's hope.
