The Xbox One has been delayed in several countries. That's a bummer. There's some good news though, as Xbox One games won't be region locked!.
"When the console launches this November, we will support Xbox One in 13 markets," Microsoft told Eurogamer. "Xbox One may be used in all countries, including the non-launched markets. In addition, Xbox One games are not region locked. Any Xbox One game purchased at retail can be used in any country on any Xbox One."
Microsoft added that you'll need a valid payment method corresponding to to a console's launch origin. That, and some content may not be available everywhere due to content restrictions some content right holders may impose on stuff like music and movies.
