Right, but there's the fact that Fire Emblem received
two newcomers (the first franchise to do so, in this game I believe), and it has three males and one female (well, with the potential, because of Robin, to have two females as well).
Also, there's this picture:
Which I speculated to be a trophy set-up on the 2D bottom section of the Wii U Pilot Wings stage. If this is a trophy set-up, it would be the first, I believe, for all of the characters on the Smash website. All other pictures are more obviously during battle, for all of the characters.
Also, if this is a trophy set-up, the people who took this picture had full control of the trophy placement. It makes me believe it was on purpose, which could be teasing us.
I don't think it could
simply refer to the stage hazard Arwing that has appeared in every Smash so far, because
we don't even have a stage for Star Fox yet. Therefore, we don't even know if the Arwing stage hazard will be back.
