Hmm how will monster cables and the like sell their stuff when the standard makes clear that existing cables can already handle the greatly increased bandwidth? I look forward to the spin!

#12> "dynamic auto lipsync" Isn't the audio and video already in sync?
On the source material, yes. But display devices may introduce some delay on the video due to scaling, de-interlacing, temporal noise reduction, and whatever other processing is done. The display device then needs to signal back to the amp how much delay it's introducing into the video so that the audio can be delayed by the same amount.

#13As someone who isn't familiar with audio technology: is there any practical use for 32 channels of audio?
It's for things like Dolby Atmos[1]. Instead of having to be stuck with a premixed 5 or 7 channel format designed for an ideal that your setup probably is not, you instead include unmixed sound and where it would ideally be coming from. The receiver then has knowledge of speaker and seating positions and dynamically mixes the output to match the room.

If you connect your source through an surround processor it helps to be able to delay the audio to match the delay of the TV which may vary depending on TV settings (e.g. Game mode may be lower delay but with less picture processing). I assume this spec allows the TV to inform the surround processor continuously of the current picture delay.

#15I wish it had 8K support, given Japan is actually already planning on starting broadcast trials for 8K in roughly two years: http://www.futureleap.com/2013/03/japan-plans-8k-broadcasts-...
It does feel a bit... short term.
We all know 4K is next, we know that clearly there'll be something afterwards, it would be good if the next hardware we buy planned for that.
Thunderbolt, BTW, has similar limits: http://superuser.com/questions/441395/what-is-the-maximum-re...

Can we just have 3D sound now, with X, Y and Z coordinates to go along with the sound clips, and the speaker system routes the right sound an arbitrary number of speakers? That works amazingly well for FPS games...

Even uncompressed and being extremely generous with the bit depth/rate: 32 ch * 24 bits * 96 kHz = 73 Mbps. That's a drop in the bucket on an 18Gbps connection.
As mentioned, this is probably aimed at theaters. Also consider that you could send four separate 7.1 audio programs simultaneously over the same link, which would let any audio program switching happen at the receiving end instead.
Actually, the Engadget article isn't very specific about "32 audio channels". Possibly they mean 32 separate audio programs instead? Audio is so cheap bandwidth-wise that it's practically free these days.

#18Anyone know how this compares to displayport? I've always heard (perhaps wrongly) of DP being technically better and patent free, so I wonder why HDMI still gets so much more attention...

#19Dissapointing that this means we won't see 4k 120 hz screens any time soon, and that most consumer hardware in the next 5 years will have compatability issues with them. I love my pixel density and refresh rate!
Probably next DisplayPort version will support them.
Re: HDMI 2.0 officially announced
#20Anyone knows if it includes any specs about closed captions? It's a source of frustration at times with the previous spec.
