Airbus always supply conversions with a new aircraft, so to say that everyone will have to start on the A330 is a little rich. For the normal guys ie you and me, yes the A330 will be the starting block, but for those stellar locals in management and other immensely senior chaps who know people who know people I bet they never see an A330, they will be in the A380 before you blink!!!
As an aside it will be a breath of fresh air for the B777 fleet to transfer some of our more popular pilots onto the A380, some went about a year ago to do the A330 route, but a few of the more special ones are still on the B777waiting waiting!!!!
