According to PWInsider, Booker T and Sharmell will be on RAW tonight. Also, Piper will be there, and there are three announce tables set up at ringside.
UPDATE:
WrestlingObserver.com has reported that the Bret Hart promo “was just shot outside a gym in Hawaii” with the idea going into the taping being that they caught him off-guard and the promo would be in-character.
Also from WrestlingObserver.com, the Iron Shiek is there and was asked to do a “crazy rant.” Uh oh.
