I wonder what this revision will cost them interms of Penalties . The original A-350 ( the suped up A330) had firm orders , the change in the Design to a bigger XWB and a delay of 4 years may cost airbus close to 1 billion dollars in penalties according to the Current EADS CFO .

Penalty payments to airlines that ordered a now-abandoned, less ambitious version of the A350 could reach up to €800 million (US$1 billion) in the last quarter of the year, Ring said
