1. Manufacture RPi with usb 3.x and deal with the associated costs, does Broadcom make a Pi'esque chip with USB 3? Say the BCM 7445 for example, does support it on chip for example(I dont know if this could even be used to build a Pi compatible device)? Are there extra license costs with usb 3.x?
2. Figure out how to use a USB 3.x connector with a USB 2.0 controller.
For the next 4-10 years the micro usb connector will stay dirt cheap, something the Foundation might find to nice a deal to pass up. The problem is everyone wants to Pi to be perfect for their wants and its not about that, its about a cheap educational product. One of my friends was torqued because web browsing on Pi2 is still sluggish and I explained that to him again.
If the power requirements (even optional additional power) go up, the current will exceed the rating for the microUSB connector. Since we're talking about a *power* connector, there is no logical connection to SoC support for USB 3.
The real fly in the ointment I see for using a USB-C connector is that the spec requires a chip in every cable, which is rather pointless in a power cable. Just wire it so that the power is correct no matter which way it is inserted and only wire the power pins.
