I applied before the early admission deadline (December) and heard back on Monday, February 11. Have you heard anything from the U of MN yet, or still on final review?
I emailed the general graduate admissions office to ensure that the delay was just a general one (because their site says 2 business days) and not a problem with my application, and they confirmed that it was just that they were processing so many admissions decisions right now. They also said that I should hear by the end of the week - hopefully that means that it switches to "decision made" tomorrow, so I can view the decision on Friday and not have to wait yet another weekend.
