I like to consider myself relatively 'in the know' when it comes to what add-ons are in development by which manufacturers. However, I have no idea if there is a DC-10 for FSX or P3D (or even X-Plane I guess) that is currently in development. I remember seeing something about one on facebook like a year ago, but I forgot the name of the dev and haven't heard anything since. Is there anyone producing a DC-10 for ANY sim? I recently took up my CLS DC-10 and remembered what an awesome plane it is. A high-fidelity DC-10 along the lines of the PMDG T7, Majestic Q400, FlightFactor 757, or even the CS L1011 would be amazing. 

 

I know CLS are updating their DC-10 quite significantly, check out their Facebook page. Other than that, I can't think of any others unfortunately. I would love a 2015 standard DC-10 too

There used to be a Project DC-XX facebook page. From what I remember the preview where quite promising, but unfortunately that page has dissapeared and nobody have heard anything about it ever since.
