I'm having no hope for Zen+ boards to supporting this, so we'll be waiting for another year?
So disappointed right now.
Unfortunately all I've seen as well are signs pointing to 2019. i.e. Ryzen 3xxx, Navi, blah.
I don't believe I'm alone with holding out on a large investment system upgrade when these are apparently not that far off. I just hope this doesn't keep dragging out and as the standard was progressively refined over the years, I find it disappointing to have a 1.5 - 2 year gap in product releases.
