I may eventually. Right now, I just graduated grad school with my MBA and looking for a job. I'm not buying any new stuff photography related at the moment. I would have to at least get a 24-70 lens as well if I do that, which will ad a lot to the total. For now, I'll be enjoying the D7000 which is serving me well.
The shallower depth of field at shorter distances from the subject will be useful when shooting FX. I do lots of full body costume portraits, where it's important to get the full costume in the frame.
