The Fantastic Locations products come with 4 maps, 3 usable with DDM, and a short adventure. As someone who has spent a good amount of drawing maps over the past month or so (and redrawing them... and redrawing them... ) I can say that there's a big gulf between an RPG map and a DDM map.
For instance, a DDM map can't have any chokepoints where Large figures have to squeeze. We also have to look at starting areas, LOS, victory areas, and the speed available to each faction. The differences are big enough that a map has to be designed for one use or the other. You can use a DDM map in D&D, but the reverse isn't true. (Well, you can, but just not in a tournament.)
For that reason, I doubt we'll bother putting that much effort into one map that goes into an RPG product. That's why we're releasing them in the Fantastic Locations products.
