A unit that is missing HDMI connectivity, has no room correction and is limited to 7.1 channels, a la your MC-4 example? I don't see why Datasat would want to come out with model that left out their main differentiators.
As for Lex doing the same, you likely have a long wait. Their original plan was to release the flagship first, then do an upscale version for Mark Levinson, and then
do the lower priced models. Until then, your argument for middle-income users necessitates comparing the RS20i to vaporware.

Would you settle for a news item about one of the technologies going into the replacement Lexicons?
A new version of ARCOS room correction has been announced at CEDIA (along with a new research paper on subwoofer placement by Todd Welti). ARCOS has been in current use on JBL Synthesis systems since April of 2011, and is the room correction technology that will be scaled to future Lex processors, Levinson pre-pros and H/K receivers.

HARMAN’s JBL Synthesis Announces ARCOS Adaptive Room Correction and Optimization System Updates at CEDIA 2012
INDIANAPOLIS, Indiana — At CEDIA 2012, HARMAN’s JBL Synthesis is announcing it has updated its ARCOS Adaptive Room Correction and Optimization System to Version 2.6 for WindowsXP, which incorporates a number of performance and user interface upgrades for faster operation and improved system calibration. ARCOS is an integrated software and hardware package that provides precise accuracy in setting up and calibrating a JBL Synthesis multichannel audio system.
In related news, HARMAN Research Acoustician, Todd Welti, will be presenting a paper at the 133rd AES Convention detailing new research into the behavior of multiple subwoofers in listening rooms. Thanks to new modeling software that Welti has developed, a larger variety of subwoofer configurations and placements can be modeled more accurately.
In all rooms, there are resonances or room modes that emphasize some frequencies and attenuate others, detracting from in-room frequency response accuracy. ARCOS v2.6 compensates for these irregularities more precisely than ever before and provides time delay correction and other benefits, to achieve flatter frequency response and extraordinary sonic realism.
ARCOS v2.6 offers 10 times faster AutoEQ calculation than previously. The time it takes to calculate a speaker channel’s required EQ compensation with up to 20 bands of parametric EQ is now reduced from over a minute to about six seconds. In addition, the AutoEQ feature now provides an Iterations function that enables the AutoEQ to calculate the multiple interactions involved in the process and get a more accurate room correction answer including how the various EQ bands interact with one another. In addition, the upgrade offers improved AutoEQ settings for better timbre-matching of the left, center and right speakers in a multichannel audio system, for more accurate subwoofer low-pass calibration and more accurate location and correction of room modes via “ringing” out the room.
In a major functionality enhancement, ARCOS now provides native support for more Harman HiQnet-capable devices in addition to the SDEC models already supported. HiQnet is a communications protocol that enables compatible devices to communicate with one another and act in synergy to deliver enhanced performance capabilities. The expansion of HiQnet in ARCOS will enable future expansion into more products and facilitate end-to-end connectivity using a unified system language.
The ARCOS user interface has also been improved. The displays now run up to four times faster, giving graphing updates and user input better smoothness and feel. All graphs can now be zoomed and panned, allowing the user to see much more detail when zeroing in on a “problem” frequency. The legends on the graphs are more legible.
The ability to compare the individual speakers in a system by overlaying their frequency response graphs is greatly improved, as it is now possible to add and remove multiple overlaid channels at once in real time. Additional interface improvements include an improved microphone calibration page, better Help menus for the final listening and source setup steps, better display of speaker crossover functions and JBL Synthesis SDEC4500 and SDEC3000 equalizer/crossover bass management functionality, and many additional enhancements.
The JBL Synthesis ARCOS Adaptive Room Correction and Optimization System is supplied with all the hardware, measurement microphones, software and accessories needed to calibrate a JBL Synthesis multichannel audio system. ARCOS is currently available to all authorized JBL Synthesis dealers and system integrators.
