Good explanation of how it works here.

I note that the Ferrari wing was shown - does this W duct actually work? If so, is it the reason their car is so unpredictable?

I note that the Ferrari wing was shown - does this W duct actually work? If so, is it the reason their car is so unpredictable? That youtube was also used here. W-duct explained « Formula One Update (http://formulaoneupdate.wordpress.com/2012/02/28/w-duct-explained/)
In the text It only suggests that the W03 has it.
A brilliant video of the so-called W-duct has appeared on Youtube, cleverly describing how the device actually works.

We´ve had the F-ducts and now it seems we have moved through the alphabet onto W. The small hole in the front of the nose cone of some of the cars this season, among these Mercedes´ W03, leads air inside the cone and onto the front wing. A W-shaped duct inside the nose then directs the air, depending on where the airflow is coming from. Watch the video below, for a better explanation.

The animation shows a Ferrari with a comepletely different nose than they have used in the tests. It will be interesting what they do in the next test, but something like that should have been part of the car concept, and could unbalance the car if it is just bolted on.
I think it should help, how much we shall see.
I think it is a clever inovation.
