Just got back from toys r us with confirmation that Video Game hardware means consoles only. Cables and such count as accessories in their categorization.
From being in the industry, the profit margin on consoles is almost zero. Like $10 or so. They plan on getting you back with profit margins on accessories and games. So consoles would be making a severe profit loss if the percent off coupons applied, and 90% of the time you'll see coupons not good on Videogame hardware for precisely this reason.
Oh and no Disney Infinity accessories were out on the show floor but an employee confirmed that they already had power discs in the back room
