Can also share what I heard couple of days ago from my source inside Toyota.
Reason for Ott's leaving is actually mainly about reliability and leadership, specially about Tommi and Mia and their ways of solving problems with Yaris and inside the TGR team (I can tell you more on that once the contract has been confirmed).
As one user said yesterday - the reasons why Toyota has failed (what we have seen on All Live) are just tip of the iceberg, and indeed alot of roadside repairs and so called praying-to-the-god is included.
New contract should be confirmed today or on Thursday.
Nothing I could confirm about Ogier to Toyota so far.
In the last 6 months 10+ people have left or let go from Toyota (middle managers, supervisors, mechanics).
The last one is mainly because of differences (Mia sacking everyone who doesn't like the way TGRWRC is operating) or because of the salary (Tommi pays average Finnish wage to most of the mechanics (unless you are his close friend) and is not willing to raise their salary even after all the success they have had).
Tanak might have burned his bridges with Toyota (more about that later on).
Akio and the Japanese supposedly came to an agreement with Tanak and his management (being first driver, having MM-motorsport to operate Yaris R5), but refused to take any action on Tommi's or Mia's leadership tactics.
// Lappi also left last year because of issues with Mia
