I think it a bit silly to assume that all 259 ordered by four airlines will account for the first 259 777Xs produced. It is very likely that there is still availability in the early airframes. CX may very well have already ordered some of those.
As for the Intercontinental at CX, wouldn't there be some face lost for
JS if we were to end up with them? I realize he's not Asian, but he lives and works in a Asian world, for now anyways.
