Will Qantas order its final eight A380s?

Qantas A380's.

Qantas ordered 20 A380's but only have 12. What other routes did Qantas ha win mind, and will they get the other 8?

I don't think specific routes were ever named. Remember QFs initial orders was in November 2000, before 9/11, before the GFC.

I think the general view is they are unlikely to get the other 8, unless the A380 (or some variant) is still in production in 2025 when they start to think about replacing the current fleet.

20 A380s would have replaced all of the older 747-400s, just leaving the 9 that were refurbished.  The next decision is the replacement of the remainder of the 747-400s, for which 777-9 should be the front-runner, with ETOPS issues to be resolved.

How many 777-9 do u think they will buy for the replacement? Around 20 would be my guess and about 8 777-8. The 777-8 would be used for Perth London, Melbourne Chicago and Sydney New York 

You think 787s they will order after the 8 arrive will be for expansion and not replacement for the 747 ERs, with the replacements for them the B777-9s?

Is a 787 really a 747 replacement? There is a massive difference in the amount of people it can hold. I really think they will buy 777-9 for 747 replacement and growth, while the 777-8 for the ultra long routes

so 787s will be more of a A330 replacement after the first 8 are deleivered?

I think more Asian routes for the 787, I don't think they will replace the a330 because they are quite new, but the 787 will replace the a330 in the future, but also serving the not as popular routes, but long range, like Melbourne DFW

you think they will convert many of the 787-9 options to b777x and 787-10?

I think they had a total of 53 orders/ purchase right/ options. I don't think they will take up all of them. The 777-9x is a must for Qantas, for bne-lax and all routes serverd by the 747. Did Qantas have the 787-10 on their mind? I didn't think so unless I am mistaken

This seems to close to the 777-9, have they built the 787-10 yet?

Most people agree that the 787-10 will be the replacement for the A330s eventually and the 787-9 are obviously meant for long thin routes. 

Do you think that qantas will buy 777x

Yes I do (777-9) for 747ER although will still depend if fuel prices stay low otherwise 787-9s will be replacement and growth of the ERs instead of growth before the B777-9s are ready for delivery. B777-9 I'm sure will replace the A380 mid 2020. And 8-10 777-8 for ultra long range flights.
