The current A3 is 5k cheaper than the A4 base price to base price. The A6 is closer by a marginal amount to the A4 (base car to base car) than the A3->A4. Thus, this would not be anything new in the Audi product line or the product lines of other auto makers.
At the end of the day, I don't think Audi is going to change their minds on this point. We are getting the sedan and there may be an outside chance at the cabrio. VW & Audi are very slow, deliberate organizations that are risk adverse. Bold just doesn't seem to be in their corporate DNA. They have spoken and the consumers will dictate if they were right. I used to view Audi as sort of a maverick but I think those days are gone.
