I hope at least Wolf returns. If more development time allows ICs to return, I'd love to see them as well. After that, I feel like we'll only get the ballot character, though I have been terrible at predicting DLC, in a good way. Before Mewtwo was announced, I figured we'd have no DLC. After he was announced, I thought he'd be the only one. When Lucas & the ballot were announced, I thought we'd only get Wolf after that. Now I'm thinking just Wolf and the ballot. At the very least, Wolf has got to be back.
By the way, Nintendo's Digital Event was kind of underwhelming, especially compared to the last two years. Having no Smash news on Tuesday really sucked.
