Christian, you could be right, especially like you say if operators go for the single class variants later on, which I believe are some way down the list. the current variants are the A380-800 which will be first to enter service with a 3 class 550 Pax capacity, then the 700 variant with 480 Pax in 3 classes and finally the 900 variant which is slated as 656 seats in 3 classes.
I guess we will just have to wait and see, especially now Boeing have announced the 747-800. All the industry reports expect the remaining major airlines (AA, BA, DLH & KLM) to announce orders in the coming year, but they are expecting this to be a battle between the 777, 787, A330 and A350 as most operators want the cost savings of the twin engined long range aircraft.
