After seeing the results of Project <whatever>, it is rather easy to see why no 2014 Road Glide. They ran out of Engineers. They needed more time to figure out how to get the Infotainment package into a redesigned fairing. A big part of the new Infotainment is the ability to do touch screen. Let's face it, the radio on the Road Glide is not exactly within arms reach. Something has to be done to make that happen. The good part is, that Infotainment deeleybob is just a flat screen, and it can be put anywhere there is room, it does not need much depth, at least it shouldn't.
As for the Twin Cooling, it will be exactly like every other Touring Model. It will only be available on the Ultra, not on the Custom (no lowers), assuming they do both models if/when they bring it back. It makes no sense to design a separate cooling for just one model, not very cost effective at all. Besides, it should work as is on a Road Glide. It may have some bearing on the fairing design, as would incorporating that vent (which should be painted to match)
