Last I checked, DL was still flying out of the North end of the A concourse in MEM. NW uses gates on A, B, and C concourses and is the only carrier on C. I think DL and NW are the only carriers on A, and everyone else, CO included, is over on C.
I'm flying out of MEM on Tues evening, so if any new developments I'll post.
