Hey Greg,
what I read was:
But even if they would stop its production, you could still use the Buildbotics.com Controller (if you like the system that much). It evolved a bit ([1], [2]) since Onefinity forked the system and it has now a 15-pin auxiliary I/O port for connection of external (e.g. closed-loop stepper) drivers.
But since they keep working on it I doubt they plan to stop it
