It's from the Torch, so take it with a grain of salt.– More than one person within WWE feels its only a matter of time before Batista returns to the organization. He’s currently in Thailand filming The Man with the Iron Fist with mixed martial artist Cung Le, his highest profile acting role to date. Russell Crowe and Lucy Liu also star in the movie.

I don't think Batista is coming back, he knows that WWE is in a youth movement and that means he won't be a focal point and would have to start putting over new guys. So he should stick to making movies, I like Wrong Side of Town and waiting for the sequel.
