It's been a little over a month since we first published a map of the 20 most expensive listings on the Cape and Islands. Since then, a gazillion dollar Powerball has minted a few new millionaires and Nantucket's priciest listing - last asking $49M - has gone off the market. In place of the Gray Lady listing, we've added an Edgartown property with it's own golf course (above) asking $12.5M. For those keeping score of the top 20, that's Cape Cod and Nantucket tied, each with seven, and the Vineyard close behind with six.
