/Greenwich's Luxury Housing Market is Fraying (I found a copy of the article that's outside the Journal's paywall, so that's what I've linked to).
There's nothing in the article you haven't heard here before: high-end houses are a drag on the market, and the outlook is bleak, but, surprising as it may seem, most people who can afford houses in this price range don't read my blog, so an article in the Journal is more likely to be noticed, and further convince them to stay put in their NYC penthouses. Especially the dreamed-for, mythical Chinese luxury market.
