Spoke with a professor today who is on the admissions committee, and just wanted to share this since I know everyone is anxiously anticipating news (maybe you already know this too but figured it might bring some peace of mind).
He reminded me that a lot of factors go into the decision of whether a student gets accepted of not, beyond numbers, letters, GPAs etc. Even when a faculty says he/she is taking a student, sometimes there's already too many students in the lab. If other faculties at the university are more open to taking students that year, the ones who already have a number of students might be less inclined to take on new students. Sometimes the direction of their research is changing, and it's hard to gauge that based on past publications. That being said, you may be a stellar applicant, but things just don't line up during a particular cycle.
TLDR: Keep your heads high! Some factors are out of our control.
