I know you've said that the board will be announced soon, but...
I'm designing a board which I intend to use alongside the HiFiBerry DAC+, connected in parallel (i.e. piggy-backed on top or underneath), and therefore I need to know which of the GPIO pins you will be using so my board does not conflict. The old "Model A/B" DAC board didn't use any of the 26 pins on the GPIO connector; is this still the case? Are you only using pins 27-40 of the new connector?
Thanks in advance for your help.
