X-Pac was invited to Friday night's RAW brand house show by Triple H. He hasn't been signed, he was simply a guest. Although, there is a movement to bring back stars from the 90's and it wouldn't be surprising if he got hired again.
Kanyon also appeared at Friday night's RAW brand house show, but as a paying customer. He bought a front row ticket and tried to do an angle of sorts. Kanyon told security that his angle cleared by Stephanie McMahon. Security didn't know if he was telling the truth or not, but they escorted him out of the building anyways.
WWE's experimental high definition TV taping at tomorrow's Smackdown brand house show may be released on DVD at some point.
