It would certainly be great to know "definitively' if ;

1) the G65 will support MQA, with or without hardware upgrade,
2) the HD621 will be upgraded to support full spec 4k HDR, (HDMI 2.1 is now in testing and it includes 1 HDR feature that HDMI 2.0a does not).
3) Most importantly, from the Multichannel MQA thread, will we actually see multichannel MQA music files, my interest is Jazz, Blues, Rock genres. No offense to classical music lovers.

Progress can be a good thing, but I can't help thinking that the roll out of 4k and related HDMI changes seem to be some sort of a joke on manufacturers and consumers.
