Still on 2019 for the time being - not everyone currently racing has 2020 yet. And some (well, me) have been having the odd issue or two getting the new version to play nice.
There were suggestions made to do a couple of short circuit races and once off races in 2020 (@Konck and @DarthMol I think - apologies if I’m remembering that wrong though). I defintely think we need to do a couple of multiplayer races and a mini-league of some sort to see what’s changed and to check if there’s any major issues with the league system. I would hate to have to put @oltman through a repeat, a repeat, a repeat of Australia again 
Of course, if you (or anyone else for that matter) are keen to get a league going in 2020 now already, there’s absolutely no reason why you can’t. You know hat they say: if you build it (a league), they will come (eventually!).
I’ve set up a new dedicated F1 2020 topic for all the new game coordinating and planning for you.
