Then there would be three drivers fighting for the title (Ogier, Tänak & Rovanperä), three other for the wins & podiums (Evans, Neuville & Lappi) and some other Rally1 drivers also. Surely Katsuta & Suninen, maybe Lindholm, Fourmaux, Loubet, Solberg, Greensmith some rounds at least.
M-Sport had their chance during this year and failed badly, so better to have Tänak driving Toyota again.
