As an update: I emailed the DGS as well and got a letter back (today, March 3) saying basically the same thing--in the top cohort, but not in the top ten, consider the terminal masters if nothing else comes up, etc. It's nice to have made it into the pool of people given more consideration, at least, but I'm not going to pin my hopes on IU rushing in with an offer on April 1st or somesuch.
In the meantime, I'll work on the assumption that I'll be joining up with the program I have been offered clear admission to (Michigan State) and begin investigating future plans accordingly. I'm attending their recruitment event later on this month, and I'm guessing that what I'll find out then will dictate how early I'll make a final statement on where I'll be attending. Weirdly enough, the two things that were most appealing to me at IU weren't technically in the history department itself: I liked the easy accessibility to the wide range of Eastern European language programs there, and I had a good experience with someone at the law school who was willing to help me dig in on the legal theory side of my project. Language acquisition is mostly a matter of personal motivation (at least, it is in my case, and MSU's language options isn't half bad either...that and Indiana is still, uh, directly south), so I can make up that half of the equation on my own/with summer study. I think that while I'm at MSU for the recruitment event, I'll see if I can work in a few meetings with con. law professors at the law school to see if anyone there has any interest in my project--if there is someone there who does, then MSU would probably actually end up becoming the better of the two options. I got the impression from speaking with people in IU's history department that they're trying to move away from nationalism stuff, and nationalism is honestly still something I still really want to address in my work.

I hope you're doing well/continuing to hear back good things!
