Exactly, would be amazing to see those tracks in 2020, but it seems unrealistic even if they have the data available. They just have data, but the track probably has to be made from scratch with new materials. I still hope we can buy the new additions to the calendar later this year via DLC. Wouldn't mind to buy 3-4 tracks (Mugello, Portimao, Imola, Hockenheim and maybe more) for 10 euros extra. When you look at other race sims (rFactor, iRacing) this is a quite common thing to do, regarding Codies probably had a budget to spend on the 2020 game and can get their new/extra investments to implement the tracks back via upsales (DLC).
