Super Smash Bros. Wii U and 3DS Discussion

but I would not hold my breath based on an old article that is as vague as that.

Means nothing, nor is it vague in any way. People would say the same thing about the leak that predicted pac-man, palutena, greninja, miis, and a few other unlikely candidates. Nintendo is traditionally anti-DLC. Don't hold your breath until it's a thing. In fact, you're more likely going to get custom skins through hacking a wii u than you are from waiting for DLC, so i would wait for that instead.
