Good news for Australian readers, and others if a high postage cost isn't a bother - Sydney bookstore Galaxy Bookshop has at least 1 new copy in stock and hopefully more, available from their online store.
www.galaxybooks.com.au
I snagged a copy a couple of weeks ago from them, but am pleasantly surprised to see they still have some in stock.
The site says that their online inventory is updated every 24 hours though, so hopefully this won't lead to any unfulfilled orders.
Postage to the US and non Asia-Pacific countries is unfortunately $AU21, meaning a total of AU$38, but since it's fetching that price or more on ABE Books, it's not too bad. Postage rates are here -

The purchasing area of the site will seem a bit basic, but for what it's worth, I've used them several times and they're efficient and trustworthy. Galaxy and their sister shop Abbeys are among the most renowned bookstores in Australia, so it's no two-bit operation. My copy arrived in Brisbane 2 days after ordering.
Hope this helps! Such a shame it has to come to such measures though. Condolences, Mr Mack.
