I think this is worse for Airbus than for Boeing. The A320 is their meat and potatoes and offsets the likely never-to-be-recouped cost of the A380. The 777 has it all over the A340 and A330 and the 787, once debugged, is sure to have a huge advantage over the A350. Boeing can afford competition in the 737 sector but Airbus cannot in the A320 sector. It's good to have a third player again!
