I see the main wiki has been updated but the 787-10s aren't due in 2019. Deliveries are starting in 2020. This has been known for over a year and has been mentioned on this thread two or three times. The recent Capital Markets Day presentation fleet plan also confirms no new 787s until 2020 with six due to be delivered that year, two in 2021, one in 2022 and three in 2023.
