From the many shots that I have seen from every car, Caterham is the one which seems to have the biggest amount of airflow going into the teatray/splitter area. I think their nose solution will be the one copied by all the teams, as the way to go.
I'm not saying it will have the boxy part and etc, but they will surely look for ways to have something as unobstructed as this:

I don't think a nose solution alone can make them really competitive, but I expect them to get away from Marussia and mix up with the midfield. Even their front wing is intricate and have much more df generator elements than Ferrari's, for instance. And we all know they wouldn't trim FW with that much df if they didn't have a reasonable amount in the rear
Yes, the car is ugly as it can be. But here we are to discuss performance and not aesthetics
