It will be interesting to see what they do with the A330/A343's.
I suspect some of them will be replaced with the B787's when they eventually start to come into service. However, as the B787 has still not flown, this could be some time off.
I think that they should at least upgrade the F/J on some of the newer aircraft that won't be rolled off for a few years. Do something similar to what they have done with the older B777-300's.
These could then be used on the longer sectors (Western Europe/Far East) initially. The non upgraded planes would continue to be used on the shorter sectors such as India & other Middle Eastern destinations.
Once the B787's start arriving, the older A330's would disappear for good.
Cheers,
