No, no, don't get your hopes up about game extras when you see a movie quite yet as was hinted at earlier, but this is deferent. Nintendo is putting ads for their Wi-Fi in theatres soon.
""The Sad, Agonizing Tale of Bhuvan Ganguly" (name of the ad) will be spotlighted in more than 5,000 theaters in the US starting July 29th through August 25th, and will be shown before such films as The Fantastic Four, The Dukes of Hazzard, Bad News Bears, Stealth, Charlie and the Chocolate Factory, and The Island."
To see the add, look here:
