New Judd engine for LMP1/what about LMP2?

[Bentley03]

I've just read an article on DSC which reveals that Engine Developments will debut a new Judd 5.5 litre engine in 2007 based on the (new for 2006!) GV5 S2.

I have no doubts whatsoever that this will be a superb LMP1 powerplant continuing the trend of class leading power and reliability. The new lump will benefit from a 10% increase in torque and improved fuel consumption, perfect for Le Mans.

Meanwhile the old 3.4 litre unit currently used by a number of LMP2 teams labours on in it's current guise.

My questions are these:
Why are the majority of LMP2 teams choosing AER over Judd?
Is there any significant development work being undertaken on the 3.4 LMP2 engine?
Is there any desire to compete with AER in LMP2?
Has the company all but abandoned it's LMP2 customers?

AER currently dominate LMP2 and I see no signs of Engine Developments (Judd) fighting back. My fears may be unfounded, but I have very real concerns for Judd customers in LMP2.
