This was mentioned somewhere else not too long ago. When I tried to find more info I did find something about Harmony discontinuing a particular remote that had voice control on it, nothing about the whole line up going away.
I have done a few systems using a Harmony Pro with the Hub and found them to be very easy to set up and they seem to work well too.
But then I have also installed a new LG TV with a Cable box and Apple TV. The LG remote controlled everything and it could be explained to an 80 year old customer how to use it, so go figure.
