Kris Zellner of LuchaWorld.com is reporting that former WWE announcer Hugo Savinovich, who now works with AAA told Miguel Angel Perez of KGBWrestling that Rey Mysterio has left WWE and he will be returning to AAA. This is the first new "news" on Rey's career status in some time. The last word on Rey is that he was still stuck in his WWE deal and he was not cashing in his paychecks.
We hope to have more word on this (and confirmation) soon.
