Bluray never needs to reach mass market. For broadcasting, on demand, and downloading HD filming and production aren't going any where. As long as there's enough people who want a disc, with certain quality levels and features (and nothing better marketed) to make it profitable, Bluray will continue. The thing with discs and Bluray pricing is that that number doesn't need to be that big. Discs do not cost that much to produce or distribute.
I would cite regulation, but I know you will simply ignore it.
