In reply to the full article; integrated Wi-Fi and USB 3.1 will not be part of the Z370 launch, but rather the H1: 2018 Z390 boards, with those two features apparently being the only difference between the boards.
I'm still skeptical about Intel moving CFL forward (August) and then suddenly it's Oct-Dec (for the boards at least). With Intel saying at Computex they'd be introducing CFL come August I am curious what they mean by 'introducing'. It depends on whether it's a hard or paper launch, however with the latter I cannot fathom confirming a chip in August and then saying it won't be available in the next quarter. Still hoping for August for both the CPU and boards, after all, it's just 1 post by a guy from 1 vendor.
