Late in February rumors came out that DFW is looking to modify gates D15 and D16 to make room for an A380. The airport refrained from announcing who the carrier was, and the carrier has yet to say anything. The possible contenders would be BA, EK, LH (long shot), QF (running into financial issues), QR. I think of those the most likely would be British Airways, Emirates (largest A380 fleet in world), or Qatar. Qatar launches service from DOH to DFW this summer, maybe they switch to the A380 in October once the new gate is functioning.

I don't know if the plans have been signed off yet and/or if construction has started, but this will be great for DFW to get an A380 service.
