I've just checked Nielsen's Bookdata, the trade database, and it looks as though the only way you're going to get a paperback edition in the near future is to get yourself airside at an international airport, because that's the only place the current paperback edition is available.
No, sorry, I checked all the entries, but nothing yet. As soon as it's in the pipeline, they'll post the information, so it's a matter of keeping on checking, I'm afraid.
