Drones will have a hard time doing precision moves due to the fact that they fly in the air. Slower, low accuracy moves that don't require precision will be possible, however for accurate moves, more sophisticated sensors and software are needed to keep track of absolute position (GPS is not very accurate). Additional sensors such as time of flight cameras which create 3D-depth maps (to about 1cm of accurate resolution currently) or multiple fixed-point sensors on the ground which the drone can use to accurately determine its position in 3D space are needed. Additional propellers for left/right/front/back can help with faster reaction control. This makes for a very complex machine- we'll see it someday however a jib is a much simpler machine. A carbon fiber jib with a tiny camera with manual or servo control would be a simpler, lower-cost solution.
