yeah this did happen, my guess is that Syracuse has an internal algorithim that attempts to predict how many acceptances will enroll, this algorithim was wrong for last year, or more correctly, it didnt adjust for that fact that kids are just applying to schools to say they applied to schools, with little to no actual real interest, the equation said this many people will enroll, that number ended up being quite a bit lower than predicted and they figured that its better to get partial tuition money if they offer lots of aid to some kids than 0 tuition money if they don't, it also looks really scummy to the kids already enrolled
