Lucky i will let u know how things on in September. I am flying ICN-HKG on 01sep currently confirmed in 2K on this flight from when it was an A330 but i dare not touch my allocation!
I also have a ICN - HKG flight on OZ. I have a business class ticket but confirmed in seat 3A and the current metal is still listed as a 747. I would be more than happy to sit in a first class seat. Hopefully i get lucky and no equipment change occurs.
