Looks like the rego's are yet to be confirmed unless anyone has some knowledge of this.

Im betting on MEL-DFW becoming a route

Where would QANTAS do have the maintenance centres based for the 787's?? Jetstar's maintenance facility at YMML?

I wouldn't be surprised if its Brisbane that gets it in terms of both line and heavy, the A330 facility is likely to get quieter over the next few years as the fleet reduces and after all it's the only facility they have left, I don't believe Jetstar have decided on who will be doing their heavy maintenance yet either, given the first heavy is due at 12 years they have a while to work it out.

How many 787s would it take to run a double daily Perth-London service?

The follow on part to this story is that QF are looking at cancelling the London A380 service from Melbourne, and originating the Perth-London B787 service in Melbourne - a bit like Air Canada's Toronto-Vancouver-Sydney service.
