Next week in le Bourget some annoucements will be made ( always are) by Airbus that will shade some light as to the A380 future.
They are working on MSN200 at the moment, with still over a 100 in backlog order, most of them for Emirates. So roughly 3 years of production.
I think price of oil in the next year(s) will be a key factor in determining the future of the beast, and if the Emirates bet works . (If it does others will have to compete or give up that segment.)
Passenger comfort might also play an unexpected role . An OPS friend in SIA recently told me that specific requests for the 380 flights over the 747 and even over the 777 on routes like FRA-SIN is becoming extremely high, same with LH I believe.
Anyway we'll know in 3 years.
