Next year’s turbo Vado SL?

Does anyone know when the next edition of the turbo Vado SL will drop? I’ve been very interested but needed time to save money, and I figured a year of refinement of my favorite design of an e-bike couldn’t hurt. The earliest reviews of the SL I’ve seen are from may 2020. So may 2021 a reasonable expectation?

Also any theories on what might be updated or what owners want changed would be cool.
