It could definitely be an unofficial waitlist situation. Like I said, somebody on here got admitted only about a week ago, so you never know!
I had a 3.69 (3.85 in my International Studies major) at a very good SLAC with Anthro/IS double majors. I have a 3.85 (non A's were in language classes) MA GPA at a top-20 polisci department. 710/770/5.5 on my GREs. I speak 2.5 regional languages in my region of interest plus Spanish. I presented at a conference, but it was an Anthro conference in undergrad. I'm comparative and focus on ethnic conflict, political violence and nationalist politics. Honors thesis, MA thesis. At least one of my LoR's is well-known in their field, and another is young but relatively well-known as well. I definitely do not have perfect stats, and when my apps went in I had an IN for one of my MA classes (later updated the transcript) because of a medical problem last year, so who knows. I doubt I get in on my numbers alone. They are fine, but hardly mind-blowing.
Hope that helps and I hope you get in!
