The current development of maps might take time to come out, but they shouldn't take as long as it's been going. I understand it's easier said than done, but I hope the dev team is aware they can reuse assets and even the same maps to make different layouts.
There are entire unused sides of the map on Grad, Castello, and Feitoria that are wasted unless you play Horde or BR. Grad has the entire village off to the side, and I'm certain a handful of people could pretty it up; plan some simple objectives and set it for testing/release. Feitoria is no different, and Castello could easily have an alternate attack/defend sequence going into the attackers camp below.
Again this is all easier said than done, and I'm by no means a professional developer but I've had my share of working with SDK's before. What we've seen/heard about the new coming maps sounds wonderful, but these options would be "easy" to accomplish and are worth looking at at the very least.
