They can't really do a 2021 model that would be a major upgrade unless they've been planning it for years in advance and that looks doubtful. The hacker code that's found at the various different model iterations like Mariko doesn't point to anything like that.
It's already May 2020, you can't just make hardware that quickly.
You may get a model with a larger screen and some other ancillary features that largely go unused in 2021 or 2022 but that's about it.
