Not very surprising at all. A Microsoft spokesperson explains Xbox One’s region protection, “Similar to the movie and music industry, games must meet country-specific regulatory guidelines before they are cleared for sale. We will continue to work with our partners to follow these guidelines with Xbox One.”
The Xbox One, up until recently has been known by speculators as the Xbox 720, Xbox Next and by it’s code name, Durango. It’s scheduled for a release date late in 2013.
