Over at the Formula One site they've got a brief summary of the changes to the regulations this year. Adjustable rear wings, KERS, and Pirelli will all be seen in 2011.
What we won't see are F-ducts and double diffusers. It also looks like Petrov and Hulkenberg lost their drive. Kind of unfortunate for Hulkenberg. Sort of saw that coming for Petrov.
Flavio still banned.
