Yes, Campaign is in development at the moment, and the turn-in date for the first draft of the manuscript is not far away. (I am trying to avoid giving absolutes, as that tends to give Murphy* stuff to play with)
Campaign Law is also getting a lot of material added to it to flesh it out. I cannot say what the final size will be right now (not having the final manuscript), but the plan is for it to be a printed product.
*Murphy as in Murhpy's Laws -- I have a number of them that show up as the random quotes on my website... heheh
