Microcenter is preselling ryzen as well - they won't presell mobos though but say they should have stock. I had pre-ordered a 1700/370x combo but cancelled due to waiting for actual numbers. In the meantime - MC has a i7 6800K and 2011-v3 x99 matx mobo for 583 out the door. That is cheaper than my 1700/370x pre-order and if I read the leaked benches right - the 6800K runs neck and neck with the 1700x/370x combo which is a tad more expensive.
