Marantz, and other CE companies, like incremental upgrades to speed replacement cycles. You want 48gb/s - buy a new box. IMO, the HDMI spec has been slow rolled for years to shorten upgrade cycles.
More to the point, when displays capable of 12 bit color become available - I'd rather not have to replace expensive electronics just to get over the 40gb/s cap.
IAC, if the next ATV can support HDMI 2.1 @40gb/s it won't be obsolete for many years. My concern is that they will go with HDMI 2.0b @18gb/s, leaving us with sub-sampled color and more limited frame rates. Unless they plan to drop the price to $99, that's a fail IMHO.
