Dirtsheet sites over the nets reported this earlier today:

WWE began airing ads today in Lake Charles, Louisiana for a May 27th SmackDown live event with Randy Orton vs. Sheamus for the World Title, Big Show vs. Kane and Natalya vs. Beth Phoenix. The same ad played later in the day with Orton vs. Sheamus replaced with Daniel Bryan vs. Sheamus.

My money was already on Sheamus, and after this i really have no doubt about it, Sheamus is gonna walk out of mania with that belt, unless of course WWE officers get pissed because of this screw up and decide to swerve and change the booking, but i don't think so...

Well, one thing's for sure, someone's gonna get fired today.
