I'd be surprised if at least the Crusaders and Silver don't end up being made. The creator of these seems to be going pretty thorough with them. If they were just doing the bare minimum they would have gone through all the main girls first and then maybe we would have seen a few other characters drip out on the side. But instead we're getting really minor background characters like Lilypad before the rest of the main girls.

At least from my perspective that gives the impression that this model maker isn't planning on stopping any time soon and we're probably gonna see a lot more down the road.
