I don't know if this has always been up, or up for some time, but FIA entry list for 2021 is out and to be fund
here (scroll down). Most interesting is that Hamilton (as we thought) is at Mercedes. We also find no change at HAAS despite Marzepin incidents. So we will see Marzepin at HAAS, racing next year. On top of that, Ted Kravitz reported on his post Abu Dhabi quali notebook that HAAS confirmed that Mazepin would be driving next year, and it's a matter of 'rehabilitation' for Mazepin, rather than a sacking.
Only two spots are yet to be 'confirmed' (I use this term losely since this is still a provisional entry list and changes still can be made). These are one seat at Red Bull and one seat at Alpha Tauri.
Other things to point out; BWT in the Aston Martin name suggets that BWT will stay with them and have a big 'sponsor influence'.
Otherwise it looks pretty much as expected.
