As per my understanding, there is no more employment based visa available for this fiscal year, which will end on September 31st. That means USCIS cannot issue any new green card until then. So, it is highly unlikely USCIS will schedule any more interview before that date and those who have already got there interview scheduled will also have to wait to get there green card issued until next year that is October 1st. And also USCIS will not accept any new I-485 application from aug 1 to sep 31.
