WWE has made arrangements for CM Punk to switch from Raw brand house shows, to Smackdown brand house shows.
With the recent suspension of Randy Orton, the Smackdown brand tour would have been suffering with top star power without the necessary changes. These changes will go into effect on June 23rd for the Smackdown show in Springfield, IL, where Punk, Daniel Bryan, Sheamus and Alberto Del Rio will be used as the Smackdown brand headliners. John Cena and Big Show will be used as the Raw headliners.
This change will only be temporary at this point, just to get through the next 60 days, since Punk is not being advertised for the Smackdown television tapings, where Cena and Triple H are being pushed as the main stars in the local markets. The plans have been for Cena to only work dark matches and Hunter to just do cameos at least for now.
The rule of thumb normally is to have one champion on each touring brand. However, all five men who are in the two title matches at No Way Out, Punk, Bryan, Kane, Del Rio and Sheamus, are all scheduled to be on the Smackdown tour this summer.
