In an interview with SuperLuchas Magazine (to view the article, click here) current AAA World Heavyweight Champion, El Zorro, confirmed that not only is he still in talks with TNA but that AAA & TNA had already come to an agreement and that he had signed his papers to make the move. Zorro said he is just waiting to find out his start date. He's expected to still compete for AAA while in TNA (much like Sarita still wrestles for CMLL when she isn't working for TNA).
I know it was reported a while back he was coming in, so it looks like it's finally going to happen. Both the X Div and Tag Div need to be built up again so I could see him in either or both spots.
