So …Mirage news. It might seem like this thread has ended but most of the news gets captured in the DCS World 1.5.x or DCS World 2.1.x threads. So this is welcome 
M-2000C Update schedule
From the ED Forum post: here
Folks,
I understand that you are anxious for news about the updates that are scheduled for the M-2000C.
Despite the AV-8B NA taking precedence in all our work schedule, the M-2000C has not been forgotten and several improvements are ready to be deployed as soon as we are able to do so:
- FM updates
- New collision model.
- Textures improvements
On the avionics side, I still have to start working on the promised changes, but they will be coming. In fact I think that the M-2000C will benefit from the hiatus since some stuff that we learned while developing the AV-8B NA will be used with the M-2000C.
Not a lot of news, but these are true news.
