if the above is true intels X299 platforms dead in the water. unless you need the top end chips the lower stuff is even more pointless than it was previously as you cant upgrade your box down the line.
Maybe they should cut their losses and cannibalise the Z270 platform.
So X299 becomes mainstream (at mainstream pricing), and X299 V2 becomes enthusiast.
Would serve them right for charging the same amount for 4-cores all these years.
