That is the whole point Pada-K-Bear, the 744 is being replaced by the B777 family and the A330/340 family, NOT by the A380.
The A380 is introducing a category of it's own and yes, the demand is for a few by each of the major carriers to satisfy a few routes which, unfortunately, won't add up to a break even figure.
I'm not swayed by large orders from Emirates etc. as they will dump them as soon as they discover they don't need them. The carriers that will count are the likes of LH, BA, AF, UAL, JAL etc. etc.
Well, that is my view, anyway!
