Airbus product line (cash cow) is based on midsized fuselage cross section twin. A300 fuselage cross section. This is what funded the A380. 4 engines (A340) dont make economic sense after ETOPS.
Airbus does not have large cross section twin. Hence the A350xwb is critical to their future, not A330neo. Large cross section ETOPS twin 777X is the real 747 replacement. A380 is a halo product and not 747 replacement. The market is too small for A380 production run vs RnD costs.
Now Airbus product line is more secure. A350xwb completes their prouct line-up. Single aisle, medium cross section twin, large cross section twin.
