I disagree.
By comitting to the A380 airbus is building just another aircraft, but bigger, in a market where no-one was really screaming for such an aircraft. Don't get me wrong, it will fly and it will sell, but in numbers to make it profitable? By sticking with it's "one flight deck fits all" policy, Airbus is actually commiting all it's furture aircraft to 80's compatible technology.
Now look at the 7E7. THIS is a cutting edge technology aircraft. Composite airframe, no bleed engines, 8500NM range at 30% cut in DOCs.
It may not be bigger or faster, just potentially much more profitable.
If you were an airline exec, which would YOU prefer?
