With the slippage in the A380 schedule, Boeing is no doubt recognising that it could be onto a good thing here; a new A380 customer would probably have to wait until 2010-11 before taking delivery; a 747-8 customer would take delivery around the same time (and could be sure Boeing wouldn't make the same mess of things as Airbus is).
I wouldn't bhe at all surprised if BA ordered it, but I'd expect CX to be one of the launchies, possibly China Airlines as well.
More bad news for Airbus today: Malaysia and ILFC are looking at cancelling their orders and ILFC is looking to do the same for the A350; it is giving Airbus until the Farnborough show to come up with a better alternative.
