It's out on the 28th Oct. Prices seem to be varying. I paid around £50 from Diabolik (they don't have it listed anymore), but Movietyme have it for £46.99. It was limited to 5,000 copies, but they almost sold out in less than a week so they doubled it to 10,000.
Both the theatrical and the Director's cut seem to have their own cased copy, which I'm happy about.
