Breaking news! It has been leaked for PC as well! No cracks yet, it is a 5.1GB retail Steam copy from Belgium (whom, if you didn't know, released the game early for some reason) It is a legit copy and it's small size is due to the amazing compression according to Todd Howard. Not sure if this really requires a whole new topic so...discuss.
It's not been verified it's real, easy way to find it is to search for the Nordic version.
But yea, there is absolutely NO confirmation it's real, and it first appeared on a website that is LOADED with fakes, so I'm not holding my breath. It got leaked 2 days ago, and since it's not all over websites yet, I'm betting it's fake.
