I have read further also. Looks like it's just a big power pack with a tether reel that powers the drone. 200' max altitude. Approx 2.0 hrs flight time.
Tether devices are over $10K. Drones that can be tethered seem to be expensive also. B&H photo sales (sell lots of DJI) says "call for estimate...no internet orders". So, I'm guessing $20K+ for the drone.
