Airbus' biggest challenge now is to sell enough of those Toulouse Turkeys to at least break even. Last I heard that number is 400+ airplanes.
The wing broke at 1.47 (I think) of ultimate load - the certification requirement is 1.5. Airbus made some structural changes to fix the problem. Even if EASA had let Airbus slide on that (which I don't think they would) the FAA wouldn't.
As for the use of composites, the technology has improved since the A300 era as well as testing techniques to detect flaws. Whether you all like it or not, plastic airplanes are the future of commercial aviation.
