That is similar to what I got. It looks like your application may have a hold on it if that was the email you received.
I stopped in to the admissions office just yesterday and she told me that interview invites might go out at the end of this week if not starting next week. She said they are still reviewing applications.
Likely if you receive an email within the next week or so you will be given a few dates to pick from in September this would be considered the "first batch" emails will then continue to go out offering interviews and batches 2nd, 3rd, 4th and so on will continue. The email that I got said "We will be extending interview offers throughout the current admissions cycle which concludes in January, 2017." So if you do not receive an email stating your status or an interview invite by late December/ early January likely all of the spots have been filled at IUSD. But that is not always the case.
The batch numbers mean nothing you could be in the last batch of interviews and still get an offer. I know plenty of people that were in the last batch of interviews that got in. It just really depends on how well you interview at that point.
Good Luck Everyone!
