Honestly, the whole gender-ratio thing in games was never a selling point or detractor, I mean, we all look the same as a pile of gibs, but in terms of gameplay, I am excited for Palutena.
The other Smash games had a few too many physical fighters. Up close attacking is always important, yes, but none that were built upon keeping them away as a better option. Mega Man seems to be a good start, with his forward Smash being a projectile and all but a few also being. Palutena, I hope, would be a trap character, or something similar to Dr. Strange in UMvC3. Lots of projectiles but not in the way Mega Man has them.
