AIrbus also indicated that they are keeping the A340 line open and are willing to subsidize fuel burn differences with the 777

Intresting! Airbus as usual is going for an all new state of the art design while Boeing relies on it's time proven dirivative approach to designing. either way neither will be flying right away. Refining designs is completely normal. Here in the western world we call it Research and Development (R&D)

What are you talking about Tim? what is derivative about the 787, its CFRP fuselage or the bleedless engines, or the new assembly process...
TextI recall an AWST article where a GE engineer talked about the problem of having an engine that would be efficient in short/medium, and long hual without big changes.

Yeap - all to do with velocities ratios and propulsive efficiencies as well as bypass ratios.
But, there are ways around that, which would make engine/nacelle aerodynamics optimal for all flight conditions, and that would improve the flexibility from short to long hauls.
