The only 380 rumour I’ve heard that has any merit is that apparently engineering have been asked to cost a return to service for 6 of them in a year or so from now. Don’t have a figure, but word is the sum is eye watering. Apparently if you don’t swing the gear up and down for a few years airbus insist on some fairly heavy maintenance. The only thing that remotely balances it is that they own them outright so no capex on brand new planes and they’ll have 6 spare parts bins to plunder which should lower the maintenance costs for the remainder of the aircraft life. Who knows which way they’ll go with it.
