DEM Mapping?

This may be a question that only Heath or Nate can answer. In a recent Map update, I noticed that we received a rather large update which also reduced the available memory. During my research to figure out why, I noticed that 3 new files were in the Descent that are the same as the 5+ series:

DEM (Digital Elevation Mapping)-

gmapdem.gma, gmapdem.img & gmapdem.sum with the size being 2.2gb (roughly). Does this mean with a future update, that we’re going to get the DEM Mapping feature?

I took out a Mk1 that I had here at the store and went into the files to confirm that this was not apart of the original maps included on the Mk1.
