The A330 is primarily designed as a short-medium haul aircraft and the wing optimised for this purpose. Although I am no expert in this regard, I am led to believe that wings good for low speed handling are not so good for high speed cruising and vice versa. This is probably why the A330 (and the A340 which has essentially the same wing) has a lower cruising speed than the 777, which has been designed from the start with long haul operations in mind (eg 777-200IGW and 777-200X). The lower cruising speed over long flights, can mean extra sector time of an hour or so, putting the A330 with its current wing at a disadvantage compared to 777.
