Guess it'll still be in service in 2040 though. TBH its not unreasonable, in service for 8 years but the design would have been frozen sometime in the mid 90's. As a consortium design there are always built in delays in major changes which are less likely to be a problem for some other companies. It should be no surprise (to a realist anyway) that things move on, the next generations of aircraft are testing elsewhere in the world.
