I don't think it will be anything active or something that physically interacts with the robots. Powering and maintaining a moving <anything> on the field over 100 matches would be pretty much impossible.

However, based on the pre-einstein presentation at the championship, it seems that moving lights or changing colors might be in the cards. In that case, I wouldn't be surprised to see an array of lights above targets, with the light indicating which one to score in. Autonomous robots would have to score in the lit goal for bonus points or something like that.

An extension of this first idea would be to have infrared lights above a series of targets. Drivers would not be able to see which is lit, but an infrared-sensing camera on the robot would be able to. Scoring into the lit goal would give bonus points.
