To be honest it is a matter of individual points of view on whether you think a certain new breed of aircraft is revolutionary or not. As someone said, the concorde only revolutionised air travel for a select wealthy few, but it is still a revolution for international flight altogether don't you think? Boeings "Sonic (the hedgehog) Cruiser" will only knock about 2-3 hours at most off a long range 747 type flight. WOW! well do you think that that is going to revolutionise air travel for the future? Maybe slightly cheaper than travelling on the Concorde but not much off an LHR-JFK flight is it? maybe one hour. Concorde can do that trip in 3 hours! As for the A380, that will bring down the prices of seats for ultra long range flights dramatically, it will mean that less wealthy people can travel further per £/$ than before, and in a much higher level of comfort (ie with bars, restaurants, gyms, cinemas and the like. Now that will be a revolution. And so was Concorde. The proposed 747X didn't get enough interset from the airlines compared to the A380. What is revolutionising about a normal 747 with 50-100 extra seats? Nothing!
