I doubt he'll comply with his statement, even if a million signatures are achieved.
Kind of like how he said he'd fight any journalist that volunteered but then refused to fight Seanbaby who happens to be trained in martial arts and not a scrawny guy like Something Awful's Lowtax.
Although really, the guy makes movies that suck but they make money apparently and people see them apparently. Not sure what fault there is in that. As if the House of the Dead or Bloodrayne franchises really deserved a lot of respect, anyways.
