HDMI 2.1 introduces 8K60, 4K120, and 'dynamic HDR' support

Variable refresh rate for games, too.

So if a good chunk of the new capabilities are down to the cable, rather than just back-end, will there be any distinguishing factors between the older ones and newer? USB was quite good about this by making the connector interiors blue, made telling the difference really easy between older devices and cables (since not everything was made fatter).

It's just one of those little quality of life improvements that makes buying replacements or sorting out the ones from the inevitable cable bag a little easier.

Moreover, the new HDMI 2.1 standard brings support for dynamic HDR metadata, enabling content makers to control levels of color, contrast and brightness on a frame-by-frame basis.

The important part here is that dynamic HDR will not require the new 48G cable to handle video in up to 4Kp60 resolution and thus manufacturers may add support for dynamic HDR even using a firmware update. That is not going to work for a lot of existing equipment because display pipelines work differently and many TVs are incapable of anything beyond HDR10. Moreover, recorded media (i.e., Ultra HD Blu-ray) does not currently support dynamic HDR (and when the next-gen standard emerges, it will bring a lot of other features, including a new content protection algorithm), which means that two primary sources for dynamic HDR content will be games and streaming media (which is an interesting thing, given the focus of AMD’s recently announced FreeSync 2 technology). It is also noteworthy that HDMI Forum does not currently mention particular HDR implementations, but only says that the HDMI 2.1 standard will support a variety of them.

With FreeSync, Adaptive Sync, and now Game Mode VRR Nvidia's GSync is looking increasingly redundant, that's assuming Adaptive Sync and Game Mode VRR are just different names for what's essentially FreeSync.

If it is basically freesync then that will eventually be a huge boost for that format when the consoles support it. Although that might be 5 years off being as they just refreshed them all.
