As we have one for F1, I thought we should have one for the series one lower from it as it's nearing its climax. Here's some of my predictions for next year:
Leaving
Lando Norris departs for F1 with (hopefully) Russell joining him there.
Alex Albon, Antonio Fuoco, Nicholas Latifi, Artem Markelov, Sean Gelael and Luca Ghiotto move on to new pastures.
Nyck de Vries leaves to join Audi in DTM/Formula E.
Max Gunther splits to race with Dragon in Formula E.
Joining
Prema field an all new line-up of Ferrari juniors Callum Ilott and Marcus Armstrong.
Carlin retain Camara and reunite with their British F3 racer Enaam Ahmed (if he has the funding) to replace the outgoing Norris.
Dan Ticktum steps up to F2 with Arden.
If they don't withdraw following Markelov's departure, Russian Time field an all new line-up of Nikita Mazepin and Euro F3 graduate Juri Vips.
Charouz and Deletraz reunite for a second season with (courtesy of connections with US Racing in ADAC F4) Mick Schumacher joining.
Campos bring GP3 racer Leonardo Pulcini to replace Ghiotto.
Dorian Boccolacci and Alessio Lorandi join MP and Trident respectively for their first full F2 seasons.
Trident also hire Ferrari junior and Euro F3 graduate Guanyu Zhou as their second driver.
Anthoine Hubert moves to ART's F2 division.
Switching teams
Arjun Maini and Jack Aitken switch from Trident and ART to DAMS for their second F2 season.
Nirei Fukuzumi switches to his old ART team.
Not sure who gets the final seats.
