Leeham.net has a seven page pdf on the subject:
• While Airbus is confident US Airways will keep its A350 order, it has not---so far as we can determine---been reaffirmed. It's quite possible the "new Delta" headed by US Airways management could place an order for the 787 and off the A350.
•Air France-KLM and nearly all of Europe's other legacy carriers are looking at the so called middle market (787/A350) category.
•Airbus has traditionally done well with the European legacy airlines, but its credibility in the twin-aisle market has taken a beating with the A380 problems and six tries needed to get the A350 right.
•Airbus is banking on the fact that the 787 line is sold out to 2013, when the first A350 is due to enter service.
•Qatar still needs to firm up its order for 60 A350s and there are conflicting reports whether Saudi Airlines will place a large order for twin-aisle airplanes this year.
•Airbus is also counting on its new A350 composite design to be at least 20% less costly than the Boeing 777, which will be nearly 20 years old in 2013---but Boeing will use the interim to improve the 777 or, perhaps, even design a composite replacement.
•Airbus' A380 has to deliver in October, there simply can't be another delay. And the airplane has to work flawlessly.
•First orders for the A330F will come this year.
