He should stay for a few years. I think the competition and cars this year a lot better than the past. VW was dominating, but we have drivers and cars that are all capable of winning.

As mknight said a few posts above, Ogier was not exactly dominating this year. He did what a champ has to do, but Tanak, Nueville or Latvala could have also been winning WDC at this stage. Latvala with reliability issues, Tanak with some misfortunes and Nueville with a few silly mistakes that led to two 1st place finished gone with the wind. Next year isn't going to be a walk in the park for the champ.
