Sin Cara has been contacting WWE about a contract extension, and it appears that the company has not been responding to him whatsoever. Officials are not interested in moving forward with the performer, and they plan to eventually phase the character out completely.
While management has given up on the character, WWE will be keeping Sin Cara around because he is featured in the upcoming Scooby Doo movie. Oficials have no plan on bringing the original performer back, so Hunico will have the role until after the movie has been released.
The original Sin Cara has pulicly stated that he owns the rights to the character. He also claims that he has proof, and that lawyers would be able to sort things out with WWE. Some believe that is the reason why the company has not been pushing the character as much lately.
While he has not been given a feud to work with since making his return to WWE, Rey Mysterio is very much still a part of the plans for Wrestlemania 30. He was penciled in for a big match against Sin Cara, but management is now looking for a new opponent for him at the pay per view.
