You can dream all you want to but in aviation history the A380 will fall into the same category as the Concord.
Hmm, let me see! Total Concorde production (including prototypes) - 20
Current A380 orders - 200.
Not quite the same category!
Like it or not, the A380 has a place in the market. Eventually environmental pressures, slot restrictions, etc will put severe limitations on the current smaller aircraft/more flights model that many airlines use and then the A380 (particularly when the -900 becomes available) will become very relevant. Why fly two 777s when you could use one A380?
