Well, obviously my source was right on point, and my surmise about it possibly being firmware only (at least for now) seem to be correct also.
Just FWIW if someone is sitting there and not already an owner, NAKAMICHI-USA on eBay has a single new Ultra 9.2 unit available for $899 + the same shipping they want for their $799 refurbished units. It doesn't say specifically, but I assume it's an open box unit they got back, maybe? Hard to resist if you are in the market, and obviously from what's been put together here, in a couple of weeks you will have a firmware update available.
PS: The amazon.com price went down $100 today, so it's $999 there now - full fare assuming that you are "Prime", with 2-day shipping included.
Given the R&D that went into this, I would be surprised if they don't come out with true (as opposed to virtual) Atmos in the not too distant future? Your mileage WILL vary, of course.
