Yes, but a crack in the monopoly edifice has appeared. It is true - the large lenses rule - for now. I anticipate larger sensors, coupled with Cassegrain reflectors(which are far lighter than glass and fold to shrink the path and can fold even more for launch - unfolding on cue) will soon be flying and will begin the cube sat's climb towards parity with the big boys as the weight saving will enable their implementation in cube sats. This will make the big boys fight back via access and price relaxations. I hope the cube sats people stay independant and do not make common cause with the big boys? Better and lower power SARs and control electronics are emerging to run within the smaller power budget of the cubes.
