One thing interesting to note is that the people behind the DigiX are also making a 3.3v to 5v level shifting shield, which could mean that people with an existing RAMPS setup could move straight to using a Due-like piece of hardware (eg: DigiX, Arduino Due or an Udoo) without needing to buy a new 3.3v variant of the RAMPS.
Whether it will 100% work with a RAMPS shield is still to be determined, Mainly, how well does the 5V-3.3V level shifting work for analog inputs like the thermistors. This is something that I haven't seen details on for the level shifting shield thgat DigiX are working on.
