If not tomorrow, then sometime during the week.
Last year [2016] notifications were released on April 18th [3rd Monday of the month]. We’re coming up on the 3rd Monday of the month tomorrow, so that would be my best guess. Having Easter in April this year (as opposed to March last year) might throw this off a bit.
Also, it’s worth noting from the last year’s thread that a document was posted on the website with the names of the scholars (much like how they posted a document with the names of the semi-finalists this year).
