This is a great move from Airbus!
As it was already said, the A330-200 is a superb plane, but many airlines don't need such big range (12,000 km) nor such amount of seats offered (240), e.g. TAP-Air Portugal on services to North America and selected African cities.
It surely will provide a very atractive replacement to A310 and B767 planes, and Airbus has some very good advantages, such the low cost to develop it (due to the huge familiarity with the existing 332/333/342/343 and future 345/346) and also because it will be alone in market (Boeing is not planing to develop a B767-200/-300 "Advanced" as far as I know, since they are just developing the new B767-400 in the 76x family; and, in this class proposed by the A330-100, they are just developing the B757-200ER, which will be a great plane but hasn't familiarity with anyother long-distance modern - I mean B767-400 and B777s - planes in Boeing line, and is also always a narrow-body and carry the disvantages brought by this, such low cargo capacity).
