Dragon Man, no-one has seen what the offer is yet apart from the AIPA negotiators. It is a bit early to be jumping at shadows.
If the new type deal includes a realistic hourly rate (commensurate with other types )and a more linear OT regime, then I believe that with fixes to some of the festering sores such as staff travel, sick leave and home transport, that the majority of pilots would support it.
As far as it being a replacement for other types:
A380: Can't see this in the short/medium term. Qantas needs a high capacity aircraft.
747: This is going anyway and these pilots would be most affected. Perhaps some transitional pay deal for RIN pilots can be worked out although that hasn't happened in the RIN achieved so far.
A330: Would eventually be replaced by 787. More in the medium term I would suggest. This is where the realistic hourly rate comes in. A330 drivers don't score much in OT and will see any extra as a win.
