With Ice Lake being 10nm, will Z390 MB have socket 1151?

Looks like Z370 is obsolete already? I was bond on starting a new build with Z370 and Coffee Lake... I still can do that, but if Z390 going to accept Ice Lake (or Cannon Lake (LGA 1151) to start with), that would be a better move then? I know it's 2H in 2018, which I am not in hurry to do a build (sort of LOL).
