Hypothesis; Toyota about to withdraw?

[plg101]

Thought struck me earlier. No tinfoil hats or conspiracy. Just based on statements as they have flowed over recent weeks.

Fact: Trulli not confirmed for 2010
Fact: Glock not confirmed, option not taken up, free to negotiate with other teams

Probable: dropping from Williams as an engine supplier

So they would not be an engine supplier, probably losing both drivers with no experienced other driver being mentioned in the silly season to replace them. Plenty of good/average/reliable drivers available.

Hypothesis: are they about to withdraw from F1?

[Project 644]

50/50. Glock's second place may have helped.
