So, my guess

Hyundai, Tanak, Neuville, Loeb and Sordo partial program. Breen R5 program and some wrc outings
Citroën stay for 2020 whit Ogier and Lappi, few WRC drives for Mads
Toyota Rovanperra, Evans, but than,.. Latvalla or Meeke, I think it will be Jari. Taka doing half wrc program.
At M-sport I think they will be happy to welcome Mikkelsen, Suninen wil have to be glad if he can stay there. Greensmith in 3th car for most rally's Paddon Meeke and Pontus whit some private funded drives.

What I hope is for nasser AL athiay to come back for some rally's, teaming up whit Meeke in Toyota's

It's just thinking out loud
