Hamill has made a HUGE announcement to his friends on twitter:

WSOF – For those that don’t know what that stands for, it’s the World Series Of Fighting – “American mixed martial arts promotion based in Las Vegas, Nevada. Its live events and competitions have been shown on the NBC Sports Network in North America and on TV Esporte Interativo in Brazil”

This is very exciting news, however it doesn’t seem as if WSOF has Hamill listed on their site just yet. As soon as he’s placed on their site, this article will be updated!
