This is what I was alluding to. There was an interview recently with Eben, where he explained that the SoC needs an upgrade to give them more (faster) peripherals and the ability to add more RAM. I can't find the source at the moment. As I understand it the SoC in the Pi was some older IP that was licensed to them (RPF/Eben) for free (or close to) by Broadcom. The RPF will have to sink so significant cost into a new SoC (and I choose to believe that this is already happening, as we speak).
