Shimbori spouts a lot of crap about a lot of things. VV is a cash cow. We'll almost certainly see one of the girls added, because $$$. KT must have a tonne of R&D to pay off, or they wouldn't be chucking stuff out the oven door so undercooked.
TN really should find a proper PR face for the main DoA series. I don't know how Shimbori is as a boss or as development lead, but he's utterly shit at marketing.
