I hope Sheik is still in the game as a second form for Zelda. They're made for each other (

), built to compliment each other's strengths and weaknesses. And, from the looks of the screen shots, it seems as though Zelda's moveset is relatively unchanged from Melee. If that's the case it wouldn't make sense to not have her Sheik transformation--having Sheik's moves is part of her moveset.
Anyway, this is a happy update.

For a minute I was getting worried that Zelda (my Brawler of choice) wouldn't even be in the game...
