If it's anything like Untold 2, there'll be a lot of clips. There are pretty much quips for every conceivable thing the story party can do, even if they likely won't, like Bert or Flavio using elemental attacks. There weren't any class-specific quips, but U2 only had 5 voices to deal with, so multiplying that by eight would obviously be a lot harder. It's the sort of thing that makes me think that Atlus USA will probably try to double- or triple-up on casting, just to keep costs down, provided they don't do what they did with 7th Dragon.
And yeah, so far, each class looks to have two outfit portraits: the more uniform one (like all of the fencers having the blue color schemes) and the unique one (like one female fencer having a red outfit and a male one basically looking like Oswald from Odin Sphere).
