The boys have actually been semi-hinting on Twitter that more TPB could pop up in the future. When asked on Twitter, all they've said is, "Stay tuned..."
I first learned this was a possibility back in May '12, when the dude filming a documentary for the guys while they toured - who was also involved working behind the scenes for TPB series - said that not only was a new movie possible, but if everything went well, a new season could also be in the cards.
I'm guessing TPB could end up being a Swearnet thing now, since the network they originally aired seems not to want them anymore (because the owner is a douche). If that guess of mine ends up being true, it's going to be MORE than worth it to become a founding fucker of Swearnet!
