Thats not the actual release date. That is the last day of the year (its also a Sunday ), no game ever releases then Its basically saying "it will be out this year".
Rumor puts it in Sept or Oct...right around Scorpio.
had to google wtf scorpio is. then again ive never owned a single xbox. I'm such a casual gamer though i only play one game a year realistically. last year was fallout this year it will be this. haven't booted it up in months.
