I'll definitely check it out.
Apparently Robert Rodriguez wrote this script before Desperado, and submitted it as Predator 3. The studio thought it would be way over budget, so they passed, and he went on to do Desperado.
Fifteen years later, they call him back and say "Hey, we were looking at doing a new Predator movie and we found your script. Wanna still do it?"
Looks pretty rad to me.
