The price shouldn't come as too much of a sticker shock to people. It's Canon, they generally price higher than their competition for similar specs.
I will be interested to see how this handles in the real world once it's released. The codec has my attention, the 4:2:2 internal is nice, and the ergonomic may prove to be better for run and gun Docu shooters.
But I have to parrot some of the other comments with my concerns. The integrated lens just doesn't seem like the best move. By making that a feature it's going to draw comparison to the considerably cheaper and very functional 4K Panasonic bridge cameras.
People who already work in a Canon workflow and enjoy the colorspace may gravitate towards this XC10, but those not already tied to Canon have other less expensive, and arguably better, options to consider. Hell, just in the internal 4k arena you could buy a slightly used GH4 and a decent lens for this price point. Or two FZ1000s and extra gear. Or even a Samsung NX1 kit, which will produce better stills and shoot super 35 sized video.
For Drone use I could see this having a purpose, but again, there are cheaper 4K options. The just announced Phantom 3 Professional shoots 4k, is almost half the price, and is a drone and camera combo. Ouch.
