Now the numbers from training are 128 upgrades for 2019 according to the OP. Training also put out around the first of the year, 175 upgrades.

I know numbers change according to fleet deliveries, block hours and other things which change the numbers some. But from the original 175 now down to 128 (20 mo Jul-Nov=100, 4mo for 7 months= 28), I just wouldn't put much stock in that being accurate. I can see it dropping more maybe. 100 total upgrades or less for 2019 is my guess.

The company also stated last year on two earnings calls that a new order would be announced by the end of 2018, which became 1st quarter 2019 and is now approximately mid year. Christie now says they are "halfway through the eval process."
