The US Xbox release is not until April 12th.
Where did you find the PC DVD version? There was no official DVD release in the US and last I heard nobody that had it in Canada, etc, shipped outside their own country. If you got it at a large chain type store then maybe region exclusivity deals have expired.
Actually you're right. I ended up getting the boxed version from GoGamer, a British website. So I guess I have the European version. I've no idea if there will be a difference between the Euro version and the U.S. version... but the copy I have is all in English, so I'm a happy camper.
