2K Sports has announced that NBA 2K13, the latest entry in the only basketball series out there whose latest entry hasn't been cancelled, broken sales records within the franchise in its first week. In fact, it sold a full 49 percent more than NBA 2K11, the previous fastest-seller, did in its first week.

13 also showed an increase of 66 percent in international sales, which either means that 2K really understands the global market, or the world just really loves Justin Bieber cameos.

Check out the launch trailer and let us know what you think.
