Without any particular team bias I'd have thought Ogier will have just as good a chance of a 6th WDC by staying with M-Sport than going to Hyundai. Mikkelsen, Neuville, Paddon and Whoever sounds like a recipe for a 'who gets the sandpit in a kindergarten' fight. Meeke will be Meeke in the C3 and Toyota have what appears to be the team that has the philosophy from a Brit Comedy show, League of Gentlemen - 'This is a local shop for local people!'
The conditions that have occurred this year will remain, sometimes a driver will shine and others they will be disappointing. The real challenger would seem to be Tanak, so far better for Ogier to stay as his Team Leader and maintain the ultra consistency approach.
