Honestly, I think the products that DJI released the last year (Inspire, P3P and P3A) were far too innovative and beyond any other device in their price range.
I am not only a proud owner of a P3A since they initially released in May 2015, but also still an astonished one since everytime I fly it I still can't belive its capabilities in terms of stability, distance, flight time, fpv quality.
I know I have spent money on it, but even today I think nothing compare to it (again, in its price range).
Looking at the Inspire world, they have pushed it even further with the "new" cameras (micro Four Thirds and thermal).
Again, I think there is little than DJI can do to improve these aircrafts, except decreasing the prices (by removing features, of course).
Probably they want to increase their presence in the cheaper aircraft market.
Just guessing.
