Yeah, one of my uncles is actually an aerodynamicist and he had a pretty hard time explaining to me, how exactly the Manta-nose / fork-nose is supposed to work and how efficient it may be. Let's just hope it won't be the final nail in Lotus' coffin.
From what I understand, the aim of the "fork-nose" is to remove as many obstructions to the rear airflow as possible, increasing the effectiveness of the rear diffuser and concomitantly increasing rear downforce. The Caterham represents a different interpretation of the same design philosophy, eliminating the front-wing pylons altogether to maximize the rear airflow.
Such a "do-or-die" approach does have its drawbacks, however. Though no one can conclusively determine the exact nature of the "fork-nose" until clearer and more detailed pictures are released, it's likely that the solution offers comparatively less potential for Lotus to generate a low-pressure area at the front. These concerns also apply to the Caterham, where the total absence of front-wing pylons not only inhibits their ability to generate front downforce, but also deprives them of a valuable mechanic by which to redirect the front airflow, as most teams have purposed the front-wing pylons to serve as aerodynamic turning vanes as well.
Certainly plenty of food for thought in your post - there have been a few who have wondered what impact having an asymmetric nose section will have on the overall performance of the car (since the second prong, as it were, is both shorter and has to terminate higher off the ground).

That no other team has adopted a similar solution may suggest that the "fork-nose" is not as efficacious as perhaps Lotus' senior technical management had originally projected it to be.
As an aside, there are suggestions that the exodus from Lotus has been quite sever recently - take it with a pinch of salt, but Joe Saward has claimed that Lotus's team has shrunk by around 80 people (including, of course, Boullier in recent months).
However, there is also a suggestion that Lotus have already lined up a replacement to Boullier - there are reports that Olivier Quesnel, the head of OAK Racing and former head of Peugeot's racing division, will be taking over the reigns at Lotus.
