One of the reasons Airbus is bumping up it's production on the A320 is to bring in the capital to develope the technology needed to produce the A350. They're a little behind in composites on a plane of that size. Since Boeing is already pushing production of composite tubes, my money is on them for the next generation narrowbody. When they do that, it may give them the positioning they need to corner that sector of the market as well. Don't forget, China has announced it's intention to enter the market as well. Probably more than 10 years out, but something to consider.
