Bret Hart Appearing on Raw?

We all know about the problems Bret Hart had in the past with the WWE. This is why it does seem strange for me that Bret The Hitman Hart might appear on the 15th anniversary edition of WWE Raw. According to the Comcast Cable Preview, Bret Hart is listed as appearing on the show. Also, according to DirecTV and TV Guide, the anniversary Raw show will see wrestlers like Stone Cold Steve Austion, Undertaker, Bret Hart, the McMahon Family, Triple H and Hulk Hogan. There are also rumors that the Rock was supposed to appear on the show but he declined. As far as we know, WWE is trying to get everybody that has been a big superstar in WWE on the show. Too bad there are some wrestlers that have signed contracts with other wrestling federations like Kurt Angle or Diesel (Kevin Nash).
