Steve, Steve, Steve, you've fallen for the claptrap, haven't you.
Not a SINGLE AIRLINE on the order book for the A380 has indicated an 800 seat configuration, they are all around the 500 seat mark for more comfort.
The only thing true about the 800 seat figure is that it is theoretical, that it is in a single-class 'cattle class' layout (i.e. pile 'em high and sell 'em cheap).
Jeeez. As for the delays, there was an issue with the aluminium use in the cabling (i.e. alu cables instead of copper) to save weight. What they didn't realise is that aluminium is not as bendy as copper is, requiring a change in some of the wiring harnesses to avoid fractures. Go figure.
But hey, good for Airbus. Now that the first one is out the door, they can only learn and improve from there.
