All 10 A380s are under "Historic" column (status is "Stored"), not under "Parked". I check the other airlines like Qatar Airways, Emirates, they are under "Parked". Lufthansa & Air France's A380s are under "Historic" column too, status is "Stored".
No A380 in Etihad's website on fleet:

No "The Residence" under "Our Cabins":

Looks like Etihad's A380 is confirmed gone. This is so sad....
