Yes it's a rumour network but are you lot for real?
Qantas have made some foolish decisions recently (eg. too many aircraft types - the exact thing that bought Ansett unstuck) but they aren't dumb enough to ditch the A380 now, especially in favour of the knackered old warmed-over 1968 Boeing. That would be like opting for the Lockheed Starliner in 1958 when everybody else was going for 707's.
As the ILFC boss Udvar-Hazy has said, the A380 will be a game-changing aircraft and those who don't have them, like those who didn't get 707's, will be the losers.
