Here’s one thought:
The A330 sounds like an aircraft – the Airbus A330 🙂 Bad name.
Secondly, judging by the number, I guess it’ll fit inbetween the A300 and A350. As it stands, those two are so close to each other with regard to features and performance, I don’t think there’s much space to fit another contender in there. So hopefully this will be all about updated ‘intestines’.
