Bret Hart returning to WWE?

Bret Hart reportedly signed a contract with the WWE. It was said that he will be appearing on WWE TV programming from January to April. What is his role? That is yet to be seen. Is this even true? I do not know that either. I guess you could call this a rumor for now but I will say that this seems to be outlandish but believable. I guess we'll have to wait til' January.
