The top story on WWE.com at the moment is about the official signing of Mistico, now to be known as Sin Cara, which they announced at a press conference in Mexico City. His new mask is similar to his old one, his history is being fully acknowledged, and the name (which means "faceless") is explained by the man himself as being a reference to the tradition and rich history of masked wrestlers in Mexico. They also have a profile and photo gallery up. Both Mistico and Stephanie McMahon-Levesque were quoted, with nothing shocking being said, though reading a quote from her about him is pretty trippy: "Sin Cara is a tremendous performer who brings the crowd to its feet every time he steps into the ring. With us, his stardom will only get bigger and brighter."
They don't usually make a big deal out of signings, especially international talent, so this looks like a good sign for how he'll be used. What brand he ends up on and how they relate him to Rey Mysterio could be key, especially since Mistico/Sin Cara is much more of a direct "replacement" for Mysterio than Alberto Del Rio would be whenever he eventually turns.
