DTV or not, it should sell good. DTV close to Expendables release or quickly afterwards may help sales. I'm guessing limited theaters though...or just promo release. No idea if it was shot in 3D...don't think it was. But I do think there's a chance it may hit theaters or OnDemand before DVD/Blu release. Assassintion Games had a promo release. Wasn't tracked, just dumped into ten theaters...made no sense. But Van Damme did some interviews. On the web. At least one.
Van Damme better be on Leno or Conan or Fallon to promote TE2.
