With 58 A380s to be in operation, I suspect that those big machines won't go to just Japan, select Asian cities, Australia, North America and Heathrow. Remember that the Boeing 777-200LR has the egde on range. Eventually, the A380s will make an appearance in Indian subcontinent (BOM), non-LHR European cities, and then regional powerhouses like CAI (and BEY if things are looking well). I expect that the A380s will also serve South America.
