I tried to get confirmation from my dealer, about what happens to 2020 orders where the buyer is forced to switch to a 2021. I still don't have an answer back. However, the point made by "Murray20c8" is valid...but only from the perspective of a person who originally ordered a 2021 and placed that order before someone who ordered a 2020. If someone was promised a 2020, I think they should get priority when the 2020 disappears and the only choice they have is a 2021. Or at least if the 2020 order was at 3000 status before it was pulled, that should give the 2020 buyer priority.
But that's admittedly my completely biased viewpoint, as a person who jumped on the 2020 bandwagon and is now in danger of being pushed off. There's no right answer to a bad and unexpected situation where not everyone will be happy with whatever is done.
