Will Airbus Build Another Double-Decker Aircraft?

Could Airbus ever build a new double-deck aircraft? This was a question some started asking anew when Emirates recently stated it would like Airbus to put the Airbus A380 back into production as the A380neo. However, it seems Emirates is very much the outlier on that, with other operators like Qatar, Korean Air, and Lufthansa keen to retire their Superjumbos. There has also been chatter about a large clean-sheet Airbus widebody dubbed the A390. But there is no evidence that such an aircraft program currently exists outside of Reddit threads. Meanwhile, there is zero interest in the North American market for an extra-big aircraft.
