Long investigations

While the Qantas incident is all very interesting, it would appear to be an accident that will be explained quickly.

The same can't be said for the British Airways crash in London in January. Since the Air Accident Investigations Branch issued its special bulletin in May, we have heard no more from them. The Wikipedia article notes that the investigators have found:
...cavitation damage to the high pressure fuel pumps of both engines, indicative of abnormally low pressure at the pump inlets. After ruling out fuel freezing or contamination, the investigation now focuses on what caused the low pressure at the pump inlets. "Restrictions in the fuel system between the aircraft fuel tanks and each of the engine HP pumps, resulting in reduced fuel flows, is suspected."
This seems a very peculiar scenario, given that it affected both engines at the same time. I am very curious to see the final explanation.
