I am optimistic we may see an announcement in the next 3 days.
If it doesn't happen this week then I surrender to those of you who said 2020
But we are coming into the second half of the week though? Isn’t it quite uncommon for Apple to issue new product press releases in the second half of a week? I’d be more inclined to say it’ll happen in the same week the new Mac Pro goes up for sale, as John Gruber has speculated. The very latest Kuo rumours about the 16” MacBook Pro being pushed out to 2020 have taken away a lot of my hope.
