As I understand it, the major candidates for dark matter are new elementary particles, so they would still fall under quantum field theory.
Of course, there is always the possibility that another revolution in physics happens, but even then our current theories will still be valid in most domains, in the same way that Newtonian mechanics is still valid in most domains.
