2016 is when CX orders are due for delivery, however I have heard that CX may be buying into some earlier production slots, but don't hold your breath.
Interestingly I heard that a strong case/presentation was put forward very recently on flying to MAN with the 777, the response I'm told was - not in the current climate in Europe, we will not start any new services to Europe in this economic climate.
As I said previously, if someone else was to start a service to the region, CX would react very quickly, until such time we must wait until 2016.
