I’m just quoting the HDMI forum on the matter that the manufacturer may opt to release firmware enabling certain features from the HDMI 2.1 set onto 2.0 devices. In this example they were referring to panels.
This is certainly interesting and help the product to stay more current. If you remember 3D wad released as a FW feature by Meridian for HD621 in a similar way.

The UHD722 is only an HDMI switch, why does it need to be upgradable?

The UHD722 is only an HDMI switch, why does it need to be upgradable? Because the UHD722 is only HDMI 2.0 and 2.1 isn't available yet and this covers all the bases for the foreseeable future.

The UHD722 is only an HDMI switch, why does it need to be upgradable? I think the example of the HD621 and adding the ability to process 3D is a good example of why this is important. Cheers Greg

The UHD722 is only an HDMI switch, why does it need to be upgradable? Because when you add new device next year it would be nice if your £2000 switcher still worked?

Can someone clarify, because it's unclear to me  Can these 2.1 features be added to 2.0 devices, or is 2.1 completely different silicon?

Can these 2.1 features be added to 2.0 devices, or is 2.1 completely different silicon? It appears so. "Version 2.1 of the HDMI Specification is backward compatible with earlier versions of the Specification and is available to all HDMI 2.0 Adopters". Source : HDMI.org ~M~

Think the question is whether 2.0 is upgradable with just firmware, ie do they have identical hardware specifications?

I suspect the answer is, some of the features of 2.1 are potentially available via firmware updates, while others will require a hardware change. For example, I will be very surprised if the current chips support passthrough at the 45 Gbps speed defined in the 2.1 spec. (In the Lumagen Pro models, a hardware change is required to go from 9 to 18 Gbps.)

Both the new Denon and Marantz receivers 'should' be able to be firmware updated to 2.1 . If that is indeed possible then it would be preferable if UHD722 could too.
It's probably too early for anyone to say definitively yet.
