Late reply, I know.
I've been in touch with communications at County about this - they say it's going to be "soon" (as in, within the next couple of months), but then again they also said this a few months ago..
At any rate, I'd expect to see it done by early next year if they keep on task. They've already got the new duplexers in the main repeater shed @ Libertyville, waiting to be swapped and repeaters waiting to be reprogrammed...
