Dart,
"Notwithstanding a Tupperware airliner too small for CX and A350s coming anyway..."
Actually, 787-10 is larger than the A330 (Ceo or Neo) for carying both passengers and cargo. It will have more range and burn less fuel than A330neo on all sector lengths. I think CX may well be interested in acquiring some around 2020. It appears the technology that has been so troublesome for the "Tupperware airliner" early on is settling and proving its worth in terms of efficiency. Note how the 787-9 for ANZ is underweight and had pain-free test program. No doubt CX will be watching closely as ANZ and other start line operations.
