I ordered one of the new boards and it is currently in route to me here. I ordered the WiFi version to get the full experience of the new hardware, although I will probably order a minima version in the next month or so.
Looking forward to getting my hands on it and seeing what the new board is capable of.
Very interested in the addition of the DAC capability as I use DAC's quite a bit and implementing them in an efficient way is always a royal pain, especially on the older R3.
I'm also interested to see if it will have any use in DSP functions, with the extra processing power available it's integration into MathLab, Octave and Scilab will be something I will be watching out for.
