If you've been looking for more space for your Xbox 360 hard drive, I bet the idea of a 250GB model sounds pretty appealing. Well, Microsoft has heard your request, and have decided to release just such an add-on hard drive! Oh, but only in Japan. Sorry about that.
Yes, Japan is getting a 250GB HDD on March 11th for $172, but us Yanks aren't getting that option. Sorry, guys! Maybe eventually.
