I think the PS3 has a customer based more "likely" to go online and order from Amazon. With the Xbox 360, the only reason to order from Amazon is no sales tax, but most stores are offering Bundled games or other bonuses which definitely will attract some sales there.
I saw some pretty solid Ad Spots for Madden...and Xbox 360? I guess Microsoft and EA have some sort of arrangement since each Madden Spot I saw (two) had advertisements for the Cores new price of $279.99 , another had Gamestop tagged on the end.
