I'm not gonna bash Emory by any means (*bows humbly*), but good LORD Duke's NT faculty is insanely good. It is just littered with all-stars.
I also got out of all my core classes except the OT and I decided to take the NT one as well. They really try to drive the paradigm thing home but I don't think it actually applies to the MTS folks. No one has given me the slightest trouble trying to take upper level courses. And if you've done work in theo/religious studies before, you can opt to be on the "MTS paradigm #2" which basically lets you do what you want as long as you do your thesis and get a few classes in each area (theo, biblical, historical).
