I asked him some time ago if there are plans for Orbiter 2016. This was his response:
Hum... that answer shows that he hasn't looked into 2016.
Terrain for 2016 is good out of the box, so no need for newer graphics. And all of the Moon is available.
What could be problematic are the EVA guys and cargo spawning on uneven terrain. So if someone from AMSO is reading this, please take a look at 2016 and do some coding tests :thumbup:
