Advertising for an upcoming 2/16/14 WWE live event in Las Vegas was officially promoting the return of Batista (Dave Bautista) to the company next year. The original internet advertising for the show featured his name and print and a photo. Any mentions of Batista online has since been removed after the story was picked up in the wrestling media. Radio advertising in the Las Vegas area continue to promote him for the show.
Batista was reportedly in talks with WWE for some time about making a return and that his filming schedule at the time prevented anything from taking place. He has another film, "Guardians of the Galaxy", that will be released on 8/1/14.
At this point he is expected as a big return for WWE in 2014 going forward.
