I got the same email today and it is in fact three letters of recommendation. I sent my recruiter five just in case, but she said it was unnecessary, so the best three are going to the board Luckily, my recruiter has been fantastic as far as getting my OML packet refreshed and ready to go. Just pending two more documents, which will be finalized tomorrow morning.
I have a 3.4 GPA and last year when I was OML'd, my recruiter told me the thing that held me back was my observation hours because they were all at one location and they were all civilian. My recruiter said the board didn't mind the lower GPA because of all of my activities, including tons of volunteer hours outside of just observing and the fact that I have balanced a demanding job and intercollegiate football. They want more than just numbers. He said they need people who can handle the demands that the program entails and my schedule and grades exemplify that.
This year, I went to the VA and observed with a former instructor there for the summer. Hopefully it's enough to go from OML to acceptance. One of last year's accepted applicants' parents worked at the same VA that I observed at and when I spoke to her, my stats were very similar to hers, but she had time at the VA for observation. It may have been the deciding factor, or at least I hope so this go around.
I cannot say much on the interview as mine was pretty much shot because my interviewer somehow did not have my packet...it's difficult for them to interview you when they don't have your information to ask questions about.
Good luck to you guys!
