It is a little strange.
The 2019 Crosstrails are on the Canadian site ... I think (!):

The aluminum ones continue as before, with two frames (A1 Premium and Premium SL).
AFAIK, the two carbon models are being discontinued, though I could be wrong about that. We won't know until the U.S. site fully updates. BTW, and oddly, you can find the aluminum 2019 Crosstrail Elite on the U.S. site's Bike Archive page:
