"Good work Lego with the "smart" hubs! I built a lot of MOC using EV3 programable hubs and EV3 motors and sensors. Also RC applications using Power+ devices. For the Control+ system I hope Lego will eventually bring to them the following features: * Programming like EV3. * Interconnection with EV3 and Power+ motors/sensors/devices. * Re-changeable pack like the EV3 hub."
