Apparently an Audio Commentary track has been recorded for the upcoming
SHOUT FACTORY BLU-RAY RELEASE!!!
I just listened to the Killer POV podcast, with guest Jeff Nelson, director of marketing from Shout Factory. According to the podcast, a commentary track has been recorded with Sam Firstenberg. I'm not 100% if it will be included on the upcoming BLU-RAY release, but it seems that it will be.
I cannot wait to purchase this release, especially if the commentary track is on there!!!
