In February last year I asked about VCS on VEX IQ. At the beginning of May there was an official reply that VCS would work with VEX IQ:

I wasn’t shocked when it wasn’t in the first non-Beta release. The next release of VCS was supposed to come out in October, and we still haven’t seen it. So VCS still doesn’t work with VEX IQ, and we have no idea when it will. Since I don’t have the unit on Robotics in the relevant class until early January, I’ve been holding off, hoping VCS would work with VEX IQ by now. It’s probably too late for me this year at this point, but can anyone give us a realistic timeframe for their compatibility?
