We got a **** ton of Smash content 2 days ago, that kinda shrinks a Wolf announcment while E3.
On the other hand, when we got Mewtwo, Lucas was announcced. When Lucas came out, 2 more came out, but we got no new announcment to be hype about. If Nintendo wanted to just fill the time until October and ballot DLC, they would have released Roy in a month and Ryu in 3 months or something. Maybe, MAYBE we get even more DLC before the ballot.
So I´m not sure xD but still hopefull.
REMEMBER: If he isn´t in during E3, we will get him announced with the n64 Stages and Tournament mode in August, shorty for Star Fox Wii U. I believe.
