I was talking to one of the local dealer's marketing guy and he said it would not surprise him if they did come out with the road glide in 2014 1/2.
He looks for it to be water cooled, fairing redesigned, and some surprises.
Now that you ask, my dealer has my number just for that event. Dealer said he had no clue if a new RG or RGU was due out but being one of their better selling baggers (at least for them) they want to see it back.
I expect a new RG, and some sort of "parts bin" bike mostly a dyna of some sort.
