The next logical step in our A3XX Master Series will most likely be the A330-X, given the similarities this fleet have to the A320 series.
Please keep this in context - we are not announcing that our next project will be the A330 - all I can say at this time is that it is likely the A330-X will follow the A320-X series, given the huge investment we have put into developing the infrastructure that these aircraft are built upon.
