I will explain my reasonings on no Dark Pit a bit further.
Is Dark Pit a really requested character? A really popular one?
I understand if Ridley fans are still hopefuls about a Ridley reveal, and all the "mistery" behind him, becaus he's EXTREMELY popular (at least in the west).
But... is Dark Pit worth some "mistery" behind?
Chances are, if Lucina was revealed right off the bat, in a combo trailer with a truly unique character, then Dark Pit's chances of getting an official Newcomer banner was missed in the Palutena trailer.
Notice how Pit was taken out of the picture at the beginning. And how Dark Pit flies in at the end.
This, between the lines, reads me as Color Swap (with DP's voice).
I am not entirely certain if that self-referential incoherence was intended; however, if that is indeed the case, Game & Watch would have at least gotten a banner for himself.
Isn't he a veteran? Tacked on to a Newcomer's reveal trailer? Why would he want to attempt to steal some spotlight? Captain Falcon didn't get a banner either.
Charizard is sort of debatable, because his announcement as a character had several attatchments to it.
Like say... no more Pokemon Trainer/Squirtle/Ivysaur with him. (And he's still sharing the trailer with a fellow Pokemon character).
