WWE's upcoming Raw show on May 17th is looking like it could be a pretty big event based on a few things. One, the show will be the second time in history that Raw has run commercial free. Also, at this point, it is the last scheduled appearance Bret Hart will have with WWE, and he has pointed out himself that his current run with the company will end on that date.
Additionally, however this might just be a mistake, on astronaut Buzz Aldrin's website, it temporarily stated that Aldrin would be guest hosting WWE Raw on May 17th. However, the information has since been removed.
