So, I'm totally new here, so if this has been covered, or I shouldn't post it here, please tell me
I am wondering whether RobotC is, or will be, supported on the EV3. I merely ask, because the download for it only specifies 'NXT', now of course that might be compatible with the EV3, I wouldn't know though.
Thanks.

RobotC will eventually support EV3. It's coming but you may have to wait for a while. I am not the authority here but I am guessing it will come sometime next year.
