The Tman Dash8-40CW was announced what, 5 years ago and is still just TBD. So there is no telling what Atlas will do when.
Dealers have order sheets for the next CZ cars that haven't even been publicly announced yet. They did this once before. The advertised order dates came and went without anyone other than dealers knowing about it. I don't even remember what it was for but I think it was the second run of F2s.
