more approvals will come

At first, congratulations.
I believe that four centers will issue approval notices for those who have submitted a response to I-485RFE. Other 485 cases that are in the half way of process and do not need RFE will be approved. Those approval notices may come a little later than you expect. Therefore, just keep patience.
But for the I-485 cases that do not start to be processed will probably suffer a delay.
