Sony has said plenty when you line up all of the information they have given on a sheet of paper. What people are craving right now are the technical specs, which I totally get, but Sony has a very clearly mapped out marketing plan and we will be getting those specs when they are good and ready to announce them. Sony announced that they would be "hunkering down" months ago and people seem to be acting surprised that Sony is hunkered down right now, even though that's what they said they would be doing.
Saying nothing to the greater market right now is a perfectly valid strategy, as is Microsoft's very aggressive strategy of blasting out a good portion of their messaging right now. Console launches are a marathon however, not a sprint, and which strategy was the right one will not really be able to be determined until a year+ into the next console gen.
Until then, everyone just needs to be patient, even if you are going a bit crazy at home in self-isolation :)
