I hope so too.Fair, fair. Honestly, I wouldn't be surprised if that all got tossed out, or at least aggressively modified due to the pandemic. It seems like at this point, manufacturers are just trying to keep up and build what they can. when they can. Both of the timings for these cars (the Z, Spring 2022 & Ariya, late Fall 2022) were announced in the midst of all this, so I'm inclined to believe that until (and sincerely hope not) we hear otherwise.
And, considering we've seen quite a few test mules out and about lately, like you said, I'd hope we're still on for spring?
But there's been a lot of "hope" going around for the last decade and I no longer think it means anything.
The Ariya was supposed to be released mid-2021, which would have allowed the Z to be after the Ariya whilst still being a 2022 model year.
