Based on the data of years prior, I'd say it's possible we'll hear from Northwestern (a poetry acceptance was actually recorded today in this year's spreadsheet), University of Oregon (acceptances/waitlists), and Indiana University Bloomington (poetry, probably). This week last year there was also some Johns Hopkins commotion, but who really knows if they'll be consistent with last year. I'd say Oregon State acceptances are possible too, considering that one was recorded on February 6th last year. Boise St and Boston University also notified acceptances/waitlists this week last year.
But who really knows! UIUC was about two weeks late notifying fiction acceptances/waitlists this year compared to previous years. So everything above may be entirely unhelpful.
But here's to hoping we'll all receive some good news this week!
