At December 2008, they found out that Scirocco was too understeery because of the Tyre Physics... So they decided to first work on Tyre Physics before getting the patch out.
As Scawen said "one thing leads to another" and each time they find out they have to change more and more things because of new Tyre Physics.
This is it... We can't blame Scawen for this...
But yea, it's really really really boring to wait 1 year for that patch...
At least it's going to be a big one! (New Tyre Physics, VWS, Another New Car, Rockingham, and who knows... maybe interiors for FZ, FX and RB?)
