Record sale for a Prospect Heights condo?

Rumor has it that three penthouse units at the Washington Condos have been sold. What if all three were put together as one unit? For some Prospect Heights-style floorplan-porn, take a look.

The resulting unit would have 8 bedrooms, 6 baths, 4400 square feet of living space and over 1500 square feet of private terrace. Price according to the original offering plan would have been $2.1MM. At recent prices, it's safe to say it's around $3MM. Has any unit from Meier's On Prospect Park sold for more than $3MM yet?
