It was also reported by FlightGlobal that CX expects to make a decision between the A380 and 747-8I in mid 2013. It remains interested in the 777X.
I guess a big question with regard to the 787-10 is whether CX goes 8 or 9 abreast in Y Class; many airlines, like UA for example, are going 9 abreast, while more "premium" carriers like BA and NH (on international routes) are going 8 abreastl obviously, on an aircraft that long, that's going to make a significant difference to the aircraft's economics.
