I don't think it means that you are necessarily on the lower end of the waitlist. The people that got a guaranteed spot for next year got their waitlist notification while they were still filling the class. I'm pretty sure that they are done filling the class, so those of you that they still deem 'acceptable', yet weren't ranked quite as high to get accepted when they were still filling, will be waitlisted. I don't know if they have started to reject applicants yet, but I thought that once the class is full they do a mass rejection and keep their favorites for the waitlist. This is what I seem to remember, but if I'm wrong and thinking of a different school's policy someone please correct me. I know that there is always a pretty decent amount of waitlist movement, so there is definitely still hope if MSU is your #1!
