I almost pre-ordered, but wavered on it and missed the cut-off But in the mean time, I noticed that the 1V power regulator for the Zynq is rated even lower than the Zedboard, and people have already encountered problems with that (see "1V Power supply under-powered" on their forums). We were planning on actually using the Zynq for some real processing, so if you're tweaking the board design, it would be really helpful if you could sneak in a regulator boost too.
(For reference, the Altera SoCKit puts an 8A regulator on their FPGA fabric. Granted the FPGA is not the star of this show, but it would still be nice to be able to use all it's got.)
