Dave Meltzer of the Wrestling Observer reports (via WrestleZone) that Batista has been training for a return to wrestling and is close to the 290 pound mark (what he wrestled at during his last WWE run). Batista has said in recent interviews that he is interested in returning to WWE and possibly working with The Rock and Brock Lesnar.
With The Rock's WWE future up in the air, and along with it, the Rock/Brock Lesnar WrestleMania 30 match, it's possible that WWE could bring Batista in to fill in The Rock's role.
Batista does have a role in an upcoming major movie -- Marvel's Guardians of the Galaxy -- which starts filming this summer.
Big news if this turns out true, although I wonder if the people will give Big Dave the same shit they give Rock for being part time.
