Itself? 21 vs 20

[Mysta]

So I've seen that you may be able to get discounts on 20s but curious what all has changed(if there's a thread I didn't see it, my apologies!) and at what point does it become worth it?

I would wait for the "big software update" to become available in the US in hopefully next 3 weeks to be able to tell what will be the differences of 2020 vs 2021.
There is a speculation that the software update will bring the 2021 features in 2020 models so the difference might be small if any. But we won't know until we finally see that update.
