lol I agree with you. Just to clear up one thing you said, though it isn't relevant in your statement, I am not talking about the mega, only the UNO series.
However, I would like a solid answer, hopefully from someone in the Arduino company. As I mentioned before, we use these boards in our company, so we would like a definite answer regarding the R1 and R2 being manufactured still. If possible maybe even an estimated prediction of how long the R3 will be in place.
