While I wouldn't be surprised that many schools will do only virtually in the fall but, to date, the only official announcement has come from the Cal State system which does not include schools like USC, UCLA, U Cal etc.
As for Washington used as one of your examples, it is quite the opposite as " among colleges moving toward resuming in-person teaching for the fall is the University of Washington, which was the first university in the nation to shift to online teaching as the pandemic arrived in the U.S." Also.. "Both Arizona schools, both Washington schools and Oregon anticipate holding in-person classes in the fall, but that leaves seven others still mulling whether to follow suit or continue holding online classes."
I live in Illinois and there have been no announcements one way or the other as to whether Illinois colleges/universities will be open as usual in the fall. I know a few people in my are who have kids that go to Michigan colleges and there have been no decisions and the only statements are that they are preparing for both virtual classes as well as precautions (social distancing, testing, reducing density etc.) assuming campuses are "normally" open.
I don't think there will be many official decisions made until the middle of June.
