It's not clear if the 390s will support Coffee Lake as well, meaning they'd be usable both with a 14nm and a 10nm architecture, but I doubt that's the case. As things look now, it's most likely Coffee Lake will get its "own" motherboard, different than everything else, which is kinda sad, but it's also the only new cpu you'll get for a year. If that's confirmed, then we'll get the motherboards right now, no reason to stagger them.
Edit: there are rumors about MSI releasing a gaming Z370 mobo right alongside the new CPUs, can't confirm it yet tho.
