I'm just curious is all.
The standard for both Dolby TrueHD and DTS-HD Master Audio is:
Up to 24-bit/96kHz for 7.1
Up to 24-bit/192kHz for 5.1 and below (where does 6.1 stand?)
Is there any reason why the 7.1 standard can't be bumped up to 192k? Please explain in as much detail as possible, and be specific.
Thanks.

Doubling the sample rate doubles the bitrate. Maybe Blu-ray sets a limit on the audio bitrate, and 5.1/24/192 fits, and 7.1/24/192 doesn't.
It really doesn't matter, though. 24/96 is good enough.
What dangus didn't say is that the human ear can't possibly hear the frequencies that higher sampling rates allow, and in fact those high sampling rates aren't really for extending high frequency response. Without getting too technical, using a modern delta-sigma DAC provides all the benefits of higher sampling rates without having to actually record all those extra bits. As the end user, as long as you're getting a sampling rate of 44.1 or 48 kHz along with a good quality DAC, you're doing just fine and don't need to have "number envy".
