Well, the A380 will come and it will be a success!
As it is right now in the developing stage, these rather insignificant little problems will of course occur as it did with any other aircraft ever build. Whatever Airbus must do to meet the specs will done, no doubt.
Surely interesting that it might have some weight difficulties right now, but it most certainly will not endanger the program nor do I think that the engineers were recalled on a emergency "please make it fly" kind of a thing.
