Update: Rey Mysterio To Sign Three-Year WWE Deal?
I can confirm and now report that Rey Mysterio is expected to sign a new three-year deal with WWE. AAA (one of the major promotions of of Mexico) had reportedly made a play for him as his current contract with WWE is expiring soon. He was said to be offered a shocking amount by the standards of Mexico, which included a guarantee of more than seven figures per year (which is what he earns in WWE).
AAA felt they needed to be offering around what he earns now to even stand a chance. How AAA would be able to afford it is not known. The general feeling is that a jump to AAA would be considered a huge risk in comparing the two companies right now. The only pros to a jump to AAA is that he would more than likely be able to do what he pleased and be guaranteed as the biggest star in the company, something he isn't always guaranteed in WWE and probably never will have.
TNA would have obviously shown major interest as well if Rey did choose to leave WWE. That is obviously not the case now with the new WWE offer.
