Shippuden Konohamaru is an existed playable ninja and 100% will be add to the game soon.

If you want to add Black Coat Sasuke, better to make him 3 star normal sasuke. So it will be : Sasuke 1 stars => Sasuke Black Suit 2 stars => Sasuke Cursed Mark 3 stars => Sasuke Shippuden 4 stars.

And more like Bandai don't want to sign another contact with Tencent, not the other way around. Or maybe they already signed and already in making of the naruto online 2 lol. Who know.
