Interesting hypothesis from F1 News about why Michael Schumacher may be retiring at the end of this season.

Some things that could break the hypothesis:
Massa being confident about his ride next year. How good an indicator is his confidence?
Kimi cannot go to Renault and so he will go to Ferrari. Therefore, the team is going to have Kimi and Massa.

Think about it as much as you want. In a few weeks it has to come out – Kimi’s home for the next year is key to fitting all the remaining pieces together.
