TNA just decided to write him off a couple of years ago and he's been pretty much on the outskirts ever since.
I was never a huge fan of his in WWF or WCW, but I've always liked him in TNA. His early run with him being always on top was rather grinding at times, but he was the only regular known star they had, so it at least made sense.
Eventually I see him returning. From the rumours I hear, he keeps getting to do more stuff in TNA by the week. I think you'll see him return to TV after BfG sometime to feud with Dixie and help "save" TNA from the mess she is/has created.
I also miss a guitar shot or two lol
