Would you rather both serial ports or the I2C/SPi? Personally i find 2 serial ports alot more useful.

Well, technically speaking it wouldn't be that hard to do all of the PWMs from one processor. The main reason for having two procs is that the user processor is designed as a "sandbox" so that no matter how hard you try, there is no way to prevent the E-stop functionality from working, the team color lights from behaving oddly etc. With two procs, all the safety critical tasks are managed by the master processor and out of the programmer's control.
