In a mildly interesting bit of news for a Friday, Intel has notified its customers that it will use an additional assembly and test facility in a bid to improve supply of its latest desktop Coffee Lake processors. Supplies of the processors have been poor.

With z390 and eight core's possibly around the corner, might be a little late on their part.

To be honest 2/3 of customers upgrade when they need and don't care what is next.
10% upgrade every generation and rest of people plan what is best for them.
I never made mistake with platforms and Z390 is excellent choice, but if someone ask me now what to do I would say to forget on Z370, Z390, Threadripper, Ryzen and to waith New Year discounts to upgrade on X299 with 10 cores.
With him customers will not be sorry when Z390 show up and still will have platform compatible with 14 and 18 Cores models.
Never know how much will used i9 cost on Ebay and other sites in future.
