Here is the response to that question from the last Q&A session:

Hans [Hartmann] is working directly with Asobo on the ATR 42- and 72-600. Making great progress. I think we will have him here maybe next time. I think it would be good to get an update. It’s our expert-level plane. It’s going to take a while to get it done to get it done, but progress is really good.
