I have been thinking about this also. I have been looking at the ARCAM processor. It handles HDMI switching. My understanding that there is an HDMI 1.1 spec, 1.2 spec, and 1.3 spec. I think I read that somewhere.
Here is what Arcam responded with when I pinged them on the new formats and if they would support the new HDMI specs:
The AV9 basically uses a high performance electronic switch to switch the HDMI, so whatever is fed in is switched and fed out of the output.
So the answer is yes, we do expect the AV9 do be able to switch future HDMI formats.
I hope this helps.
