Surprised this hasn't been posted here.
Emirates and United recently announced a partnership. Basically, United will start operating a flight from EWR-DXB in March 2023 and passengers from both airlines can connect on the other one from their hub(s) starting November 2022.
Chicago was one of the three main cities Emirates specifically named as a prime connection spot since it's one of United's largest hubs, so I wonder if this means they'll send the A380 to O'Hare to add capacity to support connections on United once the second A380 gate in the Terminal 5 expansion opens since British Airways is currently using the other A380 gate.
Emirates is bringing the A380 to Houston starting December 1st, so I don't think it would be out of the question for it to come to Chicago as well.
