Do not expect to see the A380-800F until the A350XWB is in service.
Err... I wouldn't expect to see the A380-800F until someone ORDERS the thing!!!
BTW, as you guys seem to have all the numbers, how many airframes are AB going to have to sell to break even? I'm sure the A380 will make money for some of it's operators (It damn well better for EK!!) but will it ever have been a worthwhile endevour for it's builder?
