Graynomad:
And so the shield compatibility problem begins.
Yep, we live in interesting times.
Brace yourself for a lot of "Is my Due bricked?, all I did was plug in the XYZ shield and now nothing works" questions.
Anyone ever see an official arduino R3 spec?
Someone just asked that on another thread, I said I don't think such a thing exists, at least not available to the public. Who needs documentation when you have the source code and the Eagle design files right
All the Arduino stuff really should be properly documented. I volunteer someone else to do it.

Well from the official Uno Rev3 board discription there is this section:
Revision 3 of the board has the following new features:
1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
But again I don't think that is a easy for beginners to understand statement/specification, and therefore the burden now falls on the shield manufacture to now state which arduino boards their shields will work with and which might damage a Due board. People selling Due boards may also have to be pretty specific about what shield types can or cannot be connected to the Due. I would not be happy with the arduino folks if I was in the shield selling business. There are going to unhappy sellers of both shields and Due boards facing newby customers asking for refund or replacements on their newly purchased Due boards.
