DJI just posted this video to their Youtube channel where they tease something called the "Phantom R." Hints start at 1:18.
I grabbed a few screenshots from the video and it looks like a Phantom 4 without the gimbal and possibly with an FPV camera.

I'm waiting for the black version of the kit and in the meantime hopefully a broken P3 will show up on craigslist. Should be a fun project.
