Do notice that these are pretty low-end boards. Imagine what the X79-UD7 will bring! My guess is that Foxconn and ASrock are showing their high-end boards, and the others are keeping theirs for later. And the Asus board's naming scheme suggests it's for a workstation or server.
True that, but I don't think I would buy into this platform over Z68 unless they're the same price or offer a substantial performance increase, In fact, I feel kinda stupid going with 1366 over 1155 at the time :\\ ah well
