I want to see some easy way for teams to determine their exact position on the field. It would greatly expand the possabilities in autonomous mode for those teams that don't want to build an
INS.
There are lots of options: a commercial Local Positioning System, fixed ultrasonic emitters around the field (used for triangulation), overhead camera data fed to the robots (ala RoboCup Soccer), a gradient on the carpet (ala RoboCup Jr), etc.
