The fate of the A380 and the possible demand for it in the future once it has gone out of production reminds me also of some cars, which are boxy, unfashionable and didn't sell well when new. However, the market suddenly woke up to their facilities and the second hand values remain stable, far outstripping the values of more mainstream cars of a similar age. Such cars include the NIssan Cube, Honda FR-V, Daihatsu Sirion (note all Japanese) which maintain some form of cult following. For people of limited means, these are reliable, spacious family cars good for dragging the famly around.
It would be more than fascinating if the A380 followed the example of these cars and it is found that airlines from countries with high and dense populations suddenly find a route between city pairs that a full economy seating plan makes economic sense to operate. Bit of a change from the showers and suites of the sandpit airlines.
