If I had to guess, I'd say that they put their 'pop culture' finger to the wind and determined that for non-gamers, the PS3/Wii launch hysteria was already tired news. Not for us, but for people who watch Good Morning America.
Maybe if the unboxing video had a smattering of soccer mom-friendly 'zaniness' to it (like Cheapy fending off a curious house cat that gets progressively more stubborn with each thwarted attempt), someone making the call on these sorts of things would've stopped sipping their Starbucks latte, exclaimed "That is so darling!", and kept the 'green light' for it.
Show biz: a cruel, vapid, and fickle bitch, just like much of its audience.
