A couple of screenshots generated in the Netherlands around Amsterdam. This is an incredibly detailed area inside OSM, and the results show. People have mapped forest types, and correctly tagged landuse, forest types and even the height of almost every building. This just shows the potential of using OSM data inside X-Plane :-)
The 1900D is a strong possibility and is on the shortlist after the Citation. The 742 is a long term project. Not something we want to rush just to get it out. It'll be a good one.
