Oh wow, obscure geek-only device made by a company that just happens to also be a movie company supports MKV. Yeah, that's totally the same thing. Sony doesn't have to negotiate with the MPAA; Sony IS the MPAA. Sony selling a device that supports MKV doesn't threaten the whole movie industry.
Strawman. And how is the BDP-S370 a geek only device ? It's a mainstream blu-ray player.
And exactly how you say it, Sony is the MPAA, yet Sony supports MKV. If that doesn't threaten the whole movie industry, Apple support for the format (remember kids, a format does not piracy make) doesn't either.
Face it, you made an argument and it came up short. Admitting defeat shows grace in these times. But keep on spinning it...
