I think we're pretty much past serious discussion at this point well of characters at least why don't we move onto something else like level design,new moves characters need,or other gameplay changes.
people see an opportunity so they're going to take it at the moment DOA5 is more susceptible to change than any other time so the question is "why not?"
as with the Miyako thing just let it go
Yeah I'm a little upset about that but I can understand their reasoning,I'm happy to see that I'm not the only one that likes her though so I doubt she'll just be forgotten.
The thing is the story wasn't exactly water tight it wouldn't be that hard to throw a new character in there though I'm personally hoping for Rachel then whoever.
