I have been making the same point, about a real 2.1, obviously 2.2 would be much better. Some may want 2.4 but if we want to stop it at one point it would naturally be 2.2 so we can one a sub on each side of the L/R speakers. The very key word is of course comprehensive bass management, those so called 2.1 are practically useless if that .1 is not a discrete channel.
The fact that there isn't any real 2.1 on the market (except for a couple like D+M's that D+M customer cannot confirm) that could not be pinged by the likes of Direct Live, Audyssey etc..
As HD said, it is a missed opportunity, I would really like
@gene to at least talk to D+M, Y about this deficiency, as he has some sort of direct line to those two manufacturers powers that be.., and it seems proven that sometimes they had listened to him and we all benefited from the new/updated features (such as preamp mode, and then a separately selectable preamp mode on per channel basis, that's examples of the latest D+M feature that have long been customer wishes, via Gene).
