Yesterday, a new Zynq based SBC/SOM was released. It very similar to MicroZed boards - just without those huge Ethernet/USB connector and added versions with Z7015 and Z7030, which is nice.
Ethernet and USB got moved to 3rd 100pin's connector on a bottom of the board, so whose who needaccess to it can get it thru carrier board.
Another difference between MicroZed and PicoZed is absense of microSD connector - it got replaced with 1G/4G embedded MMC (eMMC).
Also a carrier card for PicoZed with PCIe and FMC connecor now available for purchase.

I'm not sure its a perfect solution for me, but very close. And it's very nice to have another option to choose from. Great job AVNet!
