^^ Big time.
If he's gonna set up residence south of the border, he'd better do it soon.
He's already past his prime and very injury prone.
These facts indicate a decreasing window of time he has left to wrestle.
Mexican promoters down the road would likely still take him to use in some capacity, but he may not be able to capitalize on the financial opportunity like he would by going now.
Regardless, there's a reason he's staying where he is right now.
