"They" (DCG) is just Eric --a one man band. And. like all the plugin makers, it's only a sideline.
We are lucky because of this because they (our 4 main ones) are personally interested and take  great efforts in answering our questions around the forums.

Jeremy (Sparrowhawke) has got new plugins on the go and I am sure the others would create various new  plugins----if significant demand was created.
