Despite internet reports among the wrestling media claiming otherwise, Rey Mysterio did not give his notice to WWE last week. WrestleView.com never reported this. There was some issues regarding pay, although he wouldn’t be the first wrestler in the comapny to have a discussion like that with WWE management. Although it isn’t drastic, revenue is down and so is pay. Top guys in the company are still earning above $1 million annually however.
