I don't know anything about the sensors, but I suspect that they have increased the number and resolution of the analog in channels just as they doubled the number of PWM outputs.

If this is true, then I think that the CPU will spend too much time sending data to receive all the data from the joysticks etc.

If there are 16 8 bit sensors, that would mean 256 bits of info without the start & stop bits. With a loop time of about 20 milliseconds that would mean about 10000 bits per second of data just from the sensors alone.

Even at 19.2Kbaud, this is a fairly high percentage of time spent just sending data.

I would guess that some subset of data is sent back to the dashboard. How this is done is anybodies guess.
