Does Rey Mysterio pretty much have the WWE by the balls?

Apparently their is a money issue with Rey Mysterio and the WWE in terms of him returning.

With the failure of Sin Cara and the lack of a hispanic face, does Rey Mysterio pretty much have the company by the balls? He's such a huge merchandise draw, as well as getting faggot spics like Juan to watch.

Plus, he could easily make a ton of $ wrestling in Mexico, so it's not like he'd starve.

Shouldd the company do everything they can to sign him?
