Even though Airbus and the media have made such a big deal out of the A380, it is currently only the fourth largest plane in the world. Order goes: Antonov 225, Lockheed C-5, Antonov 124, Airbus A380...
And the A380 is not getting as many orders as Airbus had hoped (still at less than 100, I think), while the Boeing 787 is currently getting LOTS of orders (over 200 so far) and the A380 has been on the market for a much longer time frame.
