Japan does it all the time, I know Pizza Hut flirted their way into Monster Hunter.
If a Monster Hunter let me grill a Pizza over a fire similar to how you grill meat in that game I'd kind of want to import just to do that.
Anyways, this is just cosmetic DLC, right? Vaguely exasperating, but I'd rather have stuff like this than, say, a unique character, weapon, or stage exclusive to people who pre-order at the "right place." And I'd protest just by refusing that offer and sticking with someone else, I've done it more than a few times with Amazon pre-orders over GameStop.
