Really? Not one response from intel? Other board manufacturers have announced or are already SHIPPING B3 stepping boards with Intel's own hardware yet this question's only response has been the thunderous sound of crickets chirping...
This site isn't very helpful and I never see any Intel tech's on here helping anyone. I am not too surprised that we aren't hearing anything from Intel about when the new B3 boards will be available. Today (3-2-2011), Asus has replacement boards ready for their customers. When are we getting our boards???? I also have a DP67BG and it's my first Intel board. I have had boards from MSi, ASUS, Abit (may they rest in peace!!) and Biostar and I find the Intel board to be of lesser quality and I will never buy another one. I will sell my replacement board and get an ASUS board instead. It's a shame too. I was really hoping the Intel board was going to be a great board but the latest BIOS update lessened the ability of the board to overclock. It looks nice and pretty with all the LED's and the Skull lighting but that's the only thing this board has going for it. They make fabulous CPU's but the motherboards are lacking.
There are a few Intel folks who frequent the forums, but the community forums are intended as a free user to user interface to assist with issues.
The Intel support team can be contacted here: http://www.intel.com/support/feedback.htm
(Also, the Intel folks who do frequent the forums try to say nothing if they don't have information to covey.)
Your distrubutor from whom you bought the board(s) should be able to get your RMA set-up.
