Hi! I can claim Washington acceptance. I received and email from the department's GPA on behalf of the Admission Committee's Chair saying I was accepted and that the official offer with funding details would be made in the next few days.
A few days ago I sent an email to the GPA asking about when to expect results. She told me that normally they send most admissions the last days of january and first days of February, in two waves. During February they make a waiting list, to finally send last rejections in March.
I am not sure if I was part of the first or second wave of first acceptances. But apparently, you just have to wait patiently, since they will take their time to make all acceptances.
Good luck!!
