Here is my conspiracy theory what happened with this team in the last couple of months:
As we can see they can't keep up the speed in the race of development. That is the biggest problem this year, as they were very close to the front runners at the first few races. Because of the big reorganization there were lot of reliability problems, but now the team started work much smoother.
After the big Monaco upgrade, they are almost stopped upgrading the car's aerodynamic because Bigois was in gardening leave and there was no head of aerodynamics. There was a need of refreshing the aerodynamic group because it was not enough productive. Maybe the revised sidepod or even earlier upgrades was Bigois last attempt, but it doesn't produced enough results, so they are offering him a much lower position and of course he wouldn't liked it.
I think with this new guy, Mike Elliot they will produce a big upgrade package for the W03, but most of their resources now shifted to next years car. But I have a good feeling that we will see some interesting things on this years car. Maybe an updated exhaust or something radical. Why? Because Brawn and Rosberg already hinted they are trying everything to come up with something that will give them some speed.
Schumacher's new contract could be a good sign for next year:
If he will sign a new contract, that means he can see some good thing that is worth a try. If he leave the sport, it will be a good sign that this team will stays the same midfield runner. That is why his new contract still in question.
