Some of you are forgetting that, appreciating the limited market, development and production costs, Boeing offered Airbus a consortium on a Very Large Aircraft but Airbus refused, "Oh no we can do this on our own", so Boeing said, "OK, go it alone" and dropped out of any competition.
Airbus thought they were producing a B744 replacement, but that had already been done by the big twins, B777, and to some extent the A330 and so on. The major airlines have a place for the A380 but in penny numbers, nothing like the numbers that the B747 was ordered in, doubtful that any one airline will ever own more than fifteen to twenty A380 and none of the major American airlines are currently interested.
You can dream all you want to but in aviation history the A380 will fall into the same category as the Concord.
