To answer a few question first, before they are even asked:
-It will not be a free update, but it will be reasonably priced and all the proceeds will once again go to the museum to keep the real thing flying.
-There have been negotiations with Flight1 to release a box set with both versions.
-Old liveries will not fit on the new model, however Tim's already busy redoing some of his old work as I understand.
-We are also working on including the new gauges that have been installed in the real thing, which were partially paid by your generous donations!

Without those it would not be allowed or even possible to fly this particular DC-2 today.
All textures and animations (105, right Rob..?) will need to be redone and some parts of the model will be enhanced in the process.
Since I don't have the latest builds I will only give you a few slightly editted teasers to show the aircraft is in fact now a true FsX model:
:d
