We've been getting this question a lot in the SCEA Applicants Thread, so I just thought I'd post it here to make it easier for everyone to see!
According to information in a likely letter this year (corroborated by a conversation with the admissions office), decisions are most probably coming out on Thursday, December 11th. It could potentially be the 12th if the process takes a little longer, but it's most likely going to be the 11th. Also, based on previous years, we're assuming it'll be at 3 PM ET. So all of you can now start planning how to escape work or school on Decisions Day!
Good luck, everyone!
