Main goals of PMDG are currently related with FSX Steam Edition, to make compatible the 737 NGX and the J41. The first one may be updated next week. No decision has been made about the MD-11 yet. These updates have needed the team members that were working on the 747-400 V2, so there is still no preview.
The 737 NGX in Prepar3D will need an update soon due to some graphics core engine differences between FSX and Lockheed Martin’s simulator that may display some artefacts like in the HGS (Head-up Guidance System).
