LGW-MCO PE seat configuration

We've travelled PE to Orlando many times and have been upgraded a few times - once to the old UC and several times to the downstairs 'B' cabin.
Since the advent of the UC suites, what is the situation with the seats in the 'B' cabin? Have they left the old UC seats there? We've just booked to fly PE in January and are in the process of booking our seats online. We know we want to be in the upstairs cabin on the way out, but on the way home when all we want to do is sleep, we'd probably be better off going for the 'B' cabin if they still have the old UC seats.
