Here's hoping.
I provided feedback a little bit ago that it might be cool for special character intros to be added. It would also help out for the DLC characters who aren't going to be added to the DOA5 story mode. For example, imagine Hayate vs Raidou and the intro is Hayate talking to Raidou about how he never got to "thank" him for breaking his back - even though Raidou doesn't remember any of it. Similar for Kasumi or Ayane v Raidou. Or Hayabusa vs Nyotengu. Or Bass vs Mila. So many possibilities to expand "story" elements without attributing to the story.
I don't think they had enough time to implement it, but would be cool if it were in I think.
