Yes, but what does that mean? It could stil be a "glorified" Beagle /
Raspberry Pi / Cubiboard type of machine --- eg. some kind of multicore ARM
processor with a builtin CAN interface. I've heard rumors that Apple is
changing processors in their Macs -- going from Intel to ARM. In many ways ARM
processors look to be edging Intel and AMD out (already happening since I
believe most smart phones & tablets are ARM based).
