I know it's unlikely the Brawn/Toyota/Williams diffusers will be declared illegal, but for giggles lets look at where the race results and standings will be if the FIA does do this-
Australia-
1. Alonso (Renault)
2. Buemi (STR)
3. Bourdais (STR)
4. Sutil (Force India)
5. Heidfeld (BMW)
6. Fiscichella (Force India)
7. Webber (Red Bull)
8. Vettel* (Red Bull)
*Remarkably earning a point over Kubica precisely because his team told him to keep going when he was in three wheeler mode.
Malaysia-
1. Heidfeld (BMW)
2. Webber (Red Bull)
3. Hamilton (McLaren)
4. Massa (Ferrari)
5. Bourdais (STR)
6. Alonso (Renault)
7. Piquet (Renault)
8. Raikkonen* (Ferrari)
*Remarkably becoming the first driver in F1 history to earn points while in the garage wearing flip-flops and eating ice cream. He truly is the ice man.
Drivers Championship-
1. Alonso, 11.5
2. Heidfeld, 9
3. Buemi, 8

If the new rules were supposed to shake things up then this would get the job done. The amazing thing is that even with the mass disqualification of the "diffuser three", Ferrari would still only have 3 points!
