Downunder, the Ref 3 hasn't made it even to the ARC site yet. We will likely see it at CES this week for the very first time. You can expect a Mk.2 version of it in anywhere from 2 to 4 years if at all.
MCHD1, I know AR introduced a REF2 Mk2 within 1 year from the Ref 2, but was the event typical and part of a past pattern, or rather unique instead? On the other hand ARC has consistently offered upgrade paths to move users of its devices up the revision ladder.
Guidocorona: The Ref 2 was not unique. If you look at the release dates of Audio Research products in the Audiogon BlueBook section you will see that this practice has involved many of their products in the past, and many times the new version appeared within a year or two of the previous model.
