It all started with "leaked" images online, claiming to be a new DJI release, code-named "Triumph". They showed what looked like a full HD video link, combined with some kind of aircraft that took a 6S lipo battery and had settings for a 4K camera.
DJI confirmed these were real photos and that they are working on a new product.
DJI has now started to release teaser videos starting to show what we have been waiting for. It looks like the name Triumph was a code name for what is now called Inspire 1.
