XBox's new spot advertising their sport themed games looks an awful lot like Apple's iTunes/iPod spot from earlier this year where CD covers pile up into a city which then turns into the iPod. You have to wonder where they got their inspiration. ;) Apple's spot was released back in March of 2006 [1].
