As Dieter Mateschitz has also gone on record as stating that he will ensure stability to the Toro Rosso team through 2009 as they look for a buyer/investor.....if we presume this to mean that the Ferrari engine deal stays in place for 2009, would 2009, ie one year until 2010 give VW enough time to develop a new F1 engine?

Guess im basically asking, how long do VW/Audi/Porsche need to develop a new F1 engine and how would thay be able to test it in a test-mule what with all the new testing limits or could they be given dispensation?

Imagine this would only be give under joint permission of all the other teams which I cant see them doing in the middle of an engine freeze!
