Nintendo project leader Takashi Aoyama recently announced that Wii games would soon feature downloadable content. If you're unfamiliar with this service (which is currently prevalent in the other current-gen systems, the PS3 and Xbox 360), this means that you'll be able to download additional content for your games via Wi-Fi.
There's no word on what games will offer DLC (though we can make guesses on a few that will and won't), nor have we heard about potential memory limitations with the inclusion of this service. Add-ons will be available for both Wii Ware titles and disc-based games, though.
As per usual, Wii owners will be able to purchase such content with Wii Points or a credit card.
Now, are you ready for the bad news?
