That would be like me asking you to prove that all these players that can’t decode internally HD audio will be paired with the newest AVR that will allow customers to enjoy half the HD experience. I’m pretty sure that polling done by BD shows that there is a growing interest for 2.0 features, or else they wouldn’t be increasing its exposure through advertising and additional releases.
Even those HDM players (both formats) that have internal decoding aren't all hooked up correctly to take full advantage of their capabilities. And those HD DVD players aren't all hooked up to the internet either. There's a better chance of a game machine (360 or PS3) being hooked up than a SA player, especially for J6P.
The timeline for 2.0 was set for October 08. They are right on schedule. The PS3 has already been updated, the BD1500 just needs the firmware update, the BD50 should roll out in June, followed by the two Sony models (one bitstream and one full decoding).
