The adopter extranet full spec link requires a log in unfortunately.
Do you know if 48 fps will be supported? No news about 10 and 12 bit color too yet I see.

1536khz sample frequency sound, now that is overkill. 192khz is still understandable in a surround setting. It allows finer timing between speakers to create clearer harmonic effects. Also more data points will better represent the original sound curve and introduce less errors during mixing. Yet 1536khz, that's one smooth sound curve, and quite the data rate. 35.1 mbps uncompressed per channel for 1536/24 sound. Though with an 18gbps pipe, 32 1536/24 channels still leaves you with almost 17gbps for picture. I guess they thought why the hell not.

4K 12 bit RGB at 60p is 16.7 Gbps, looking good for 12 bit support, not for 120fps support.
Even at 8 bit RGB 4K120p would be 22.2 Gbps, too much, so no 3D 4K at 60 fps per eye.
(3D 1080p at 60 fps per eye should be in there. That was the reason for the 1.4b spec that morphed into 2.0)

I wonder what support for 21:9 will entail, 5040x2160 spec maybe? Won't fit in the pipe at over 8 bit at 60p.

oh, 48FPS so we can watch The Hobbit!

Hmm, I don't see why it shouldn't be able to downscale, but I don't know of any TV that could match that.  The closes would be 50p which is more common in Europe.  Do you think a 60P TV could adjsut to 48P? (or 96p for 3D)  I just don't know enough about the current interals and limits.

"1536khz sample frequency sound, now that is overkill."  Well, you know, they want to keep the dogs, dolphins and bats entertainerd. lol.  Plus, if you smile next to the speaker it could give you an ultrasonic cleaning. :D

It was supposed to do Deep Colour 30/36/48-bit up to 4K60, but I don't see that confirmed.  Also support for xvYCC, but not sure about that either.

Seems like they kind of overkilled in some areas, and missed the mark in others.  It will probably be a while before I get a new device and by then it will probably HDMI 2.2 or something.

So are you happy? Sad? mixed? 

A 240hz tv should have no problem with 48fps, that's simply repeating every frame 5 times. Although most tv's can do 24hz with a normal maximum of 60hz, adjusting the timing logic to 48hz shouldn't be a problem I think.

It's a shame 1080p120 or even 1080p240 isn't supported. It would help with games, instead of dropping from 60 fps to 30 fps with vsync enabled, games could also do 40 fps with a 120hz mode or 48 fps with 240hz mode. It would be even better if there was a mode to unlock frame rate completely. Send the frame when it's ready, and the monitor updates the screen as soon as the frame has been received, end of screen-tearing once and for all. The days of fixed refresh rates from CRT are long gone.

Dogs and Dolphins needn't worry, most speakers only go up to 42khz at most. The higher sample rate is beneficial to the timing between speakers, gives a more accurate representation of the sound waves, and introduces fewer artifacts with further signal processing and during DA conversion. There won't be any ultra sonic sound coming out of your speakers.

48 bit (16 bit per color) is also too much bandwidth for 4K60,  36 (12 bit per color) for 4K would be very nice anyway.
Mixed feelings indeed, everything still locked to max 60hz means screen tearing in games is here to stay. Anyway at least 4K60 is coming.
