Congrats on the acceptance! I finally created an account so I could reply to this, because I do have the tiniest bit of information here.
I also got accepted to LSU, but before I applied I visited the department. I met with the DGS who didn't seem too optimistic about funding opportunities because of budget cuts that were being made. I got accepted without funding, which wasn't much of a surprise after that meeting (also being an MA applicant I knew funding was a little less likely). I also met with several current students, a good bit of whom weren't on departmental funding, but were being funded through other places in the university (like the library or the graduate school).
So I'm not sure when you'll get official word on funding, but I know that they don't have the money to fund as many students as they like, so you might want to look into other options just in case.
