They will want something big to announce and advertising its opening
Well at least they've got 2 years to sort something out; I honestly can't see any necessity for a scheduled cargo operation from China, but unless thing change radically, I would be just as surprised not to see an A380 on DXB, almost certainly coinciding with the opening of the extended runway.
As for anything else of substance, as I said before, the jury is out, though I can't say I'm quite as pessimistic as crewmeal.
