HPS Civil War series - current development/support?

[BigDuke66]

I was looking thru all the games of the Civil War series and what wonders me is that all the old HPS games have their last patch that really added/changed something from 2009 or before, the 2010/2011 patches seem just to add Mouse zoom and remove CD check.
I had expected to see at least some games with newer patches that really added/changed something just like it is with the Napoleon series.
So except for the Overland Campaign from JTS, does anyone know if there is any work done or planed on the other Civil War games?
