Devin Cutting is reporting that the advertised line-up for the WWE Supershow in Salisbury, MD and in Wildwood, NJ is featuring a tag team match of John Cena and Rey Mysterio vs Big Show and CM Punk. This booking would indicate that CM Punk is in fact turning heel on Smackdown following his World Heavyweight Championship win at "Extreme Rules," however, as is often the case with WWE, creative plans can and do change.
