"Still hope? I think a single word can answer that: No"
Really? By what means of clairvoyant insight have you determined this? Certainly the SC
is highly unlikely in the near term, however beyond the next 10-15 years, assuming sustained air travel growth, there may indeed be a niche for a faster airplane, especially with business travelers. You can't rule out such a concept simply because current market conditions have caused it to be shelved for the time being.
"Teahan's right. I'm not too optimistic about the so-called 'Dreamliner' either. If Airbus bring out a similar machine but with cockpit commonality with the A32x and A330/340, it'll sell about as many aircraft as the 767-400."
Again, it's impossible at this point to declare the 7E7 a non-starter, particularly if Boeing can meet the economics projections it claims. And even if Airbus can bring out a similar airplane, it will be AT
LEAST several years behind Boeing in doing so by which time the 7E7 is likely to have a solid customer base. Since improved economics are what airlines want and need most, airlines should flock to this airplane like children did to the Pied Piper of Hamelin. No doubt they'll also buy the Airbus competitor when it eventually comes out but that will take time, during which I'd expect Airbus to keep trying to sell the A332 at reduced prices until it's free of the A380 overhead.
