"should have come from our leaders"
Where do you think it came from?
First of all, these guys are very busy indeed.
Second, if you are really that curious, you call them on the telephone and our leaders will tell you.
Third, there is a real danger in setting expectations that there is going to be an announcement at every change, including recheduling meetings of importance. If you start that expectation, then you leave yourself open to the charge of manipulating the flow of information when it doesn't happen all the time. Better to give periodic reports, and if you want more than that CALL THEM UP.
