I'm an anecdata point for the "my drones are getting smaller" side here: My first couple of quadcopters were 10 and 12 inch prop sized, weighing in around 2 or 3 pounds - all me recent ones are _much_ smaller - 6 and 5 inch props with my "light" one being just under 200g (under half a pound) and the other three in the 1 to 1.5 pound range (depending on battery size and how much gear it's got on board - gps/video adds extra weight)

Tiny drones are much more common now as well - I've got a drawer full of Cheerson CX10s which weigh all of 30g or so (about an ounce). I strongly suspect the bulk of the "700,000 drones sold" are made up of devices closer to my CX10s than they are to "washing machine sized" ones capable of getting to 10,000 feet.
