Just my 2 sens worth.
Asia is the future market. or at least Asian carriers. It is significant that Malaysian, Singapore and QANTAS are among the lead purchasers.
Ever heard of the Kangaroo Route, all three operators thrive on this, and the numbers are not going down.
Have you tried a flight from South Africa to Asia, all the flights are full, I do this regularly and upgrades are becoming standard, there just aren't enough seats for the pax.
Good luck to the A380, Asia is the future.
