I thought I had read a company release that the first A-350 sim was already at TK, and the bay was being prepped.
"At" meaning still in crates, and not operational.
That being said, I would think the sim installation would be "full speed ahead!" until the moment they decide to cancel the order. They'd have to, in case they don't cancel.
I hope we get them, and 321s. I think 330s are unlikely...too similar to 777 or 787, and just one more fleet to support/bid/train pilots for.
