I smell a hoax somewhere.
Unless there is some specific saftey concern, whitch there hasnt been one so far in the 18 month history of blown diffusers and retarded engine mapping.
I seriously doubt that anything can be taken from this.
You realise that would mean that teams like Williams, Sauber, Team Lotus and STR that dont have a great deal of money arround have just wasted a decent ammount of cash to develop a EBD, not to mention Virgin who have spent a sizeable ammount of their budget to develop one for their car.
If there is a ban, ill eat my words. Just Tewwted a few people that could find out, and are relyable.
