Makes sense, as the Taurus ends production in March 2019, so I figure the plant will switch over soon after.2 sources:
2020 Aviator will arrive summer/fall of 2019
Explorer (and Aviator) Job 1 is second quarter of next year.
Now the question is at which auto show the production Aviator debut, as the Explorer needs to debut too still! And the new Escape, and the new MKC replacement, and the Bronco...2019 will be a busy show season!
