Last year was on the 11th, which was a Tuesday, and the PR came out after hours. 2016 was on the 15th which was a Friday. 2015 was April 14th which was a Tuesday.
I think they have until the 15th to release them and with everything that has been going on, it wouldn't surprise me to see them release them after hours on Friday.
Today would be interesting.
I guess we'll know within the next hour or three.
