CS has stopped all P3D developments no 737 freighter coming...

Although CS has tip-toed thru this subject, all indicators suggest exactly this.
No official word that they have ceased all P3D development, but then again, ever since the MSFS exterior models made their arrival, I can't recall any meaningful updates to P3D projects.

Seeing how they handled the last "Freighter" for P3D, I think if the 737 customers get anything at all, it will be a texture map with a cargo door painted on it.  Heck, I can do that myself (and have with other projects).

Can't wait to see the reactions in the P3D 737 forum when CS releases the 737 series for MSFS.  :o
Wait for it.......
