I'd like to take a moment and say "Can we please get more F-Zero pilots up in here!?"
It's been just Captain Falcon until Brawl (while he wasn't outright confirmed, I can already tell he's still in) and he's far from the coolest pilot, I'll be honest. There's so many cool pilots they could use. Spade, The Skull, Black Shadow, Pico, Super Arrow, Mighty Gazelle, Blood Falcon, Phoenix, and so forth. Hell, why not make Deathborn one of those stage bosses? That would sure be fun!
