Pre-order DLC is a simple way to advertise a game. I can imagine the TV commercials ending with "Pre-order now on select retailers for bonus DLC costume sets!"

Select retailers giving out the bonus DLC will definitely advertise the game through in-store posters, magazines, and internet ads so consumers will buy it at their stores. But it's up to Nintendo to market the game even further.

What do you guy's think?

I think Nintendo is getting desperate.

I hope they advertise it heavily now so at least everyone can comprehend which dlc they have to buy for what and from which retailer to preorder from.

I hope they do, but its nintendo! You never know...

They've been advertising the piss outta it on YouTube.

Like Internet ads or youtube trailer videos?

The Latter.

I have ad blocker so I have no idea on the former.
