My guess is that defences against those size and larger drones will improve to the point where they're null without total air supremacy. You can't safely fly a Jet these days without enormous support, interference and then at great risk until the skies are very well cleared. I think possibly the same thing will apply to drones in that 'just as cheap' technology will render them null. Maybe not for the 'very smallest' type drones but certainly anything approaching the size of a car that sticks out on radar - a slow, lumbering, easy target for a range of weapons. It's one thing for Azerbeijan or Libyans to face these things, much like American air power over Iraq, it's not a 'balanced situation'. The moment someone tries to use these against a capable adversary we'll see what toys are hidden away and/or things will change very quickly.
