So under the version info where is still says "unreleased" it needs to be updated. I am going to guess there has been no U.S. distribution though, and that maybe there is a limited amount in circulation since there are none available in the marketplace.
I don't think I am hot enough to order from overseas, but then I need to check the price before on amazon.de before I rule it out altogether.
Definitely released - but at the moment we don't have an US distribution. At the moment, the game is available in Germany.
