1. drivers title - Tänak takes it back
2. manus title - Toyota takes it back
3. we will have new rally winner (someone who have not won yet), Rovanperä or Breen
4. Solberg is best in R5 category in some rally (edit: Rally2 or whatever way you call 2020 WRC2+WRC3)
5. Additionally to already announced WRC drivers, there will be at least 2 new drivers (gentleman drivers excluded)
not that well measurable:
* WRC2/WRC3 will be more interesting and competitive than WRC
* Ogier may want to get team-orders, because Evans and Rovanperä are taking valuable points away and this is the reason why he loses title
