Well we just released a patch just two weeks ago for WOTR (!), and we are working on another to be released soon. We are also working on an add-on/expansion for WOFF. We still have plans to expand WOTR still plan on a Battle for France and other ideas, as long as we can keep going.
Obviously if everyone holds off buying it we won't be here to do that!

Edit, V1.17 is out now (2 updates in 2 weeks not too shabby).
