As many have commented Inibuilds are approaching the marketplace with a good deal of insight. However I believe you have missed a great opportunity by not marching full speed in bringing the A380 to market. It is truly a natural progression and makes better sense that the other aircraft in the works.
Don't miss this great opportunity, don't put the A380 on the back burner. You have a significant number of existing clients that are keenly waiting for the A380 (myself included).
Respectfully,
