Its unlikely he will release the report during trading hours.  Possible, but unlikely.  Most news, specially earnings reports, are released before of after trading hours.

It looks like he is not going to release it early, or he would have kept his own schedule when he posted it would be released 3/29, so to me that indicates he will release it after close on Monday, since he posted recently that it wasn't "due" until Monday.  Monday at 11:59p is still Monday.  I suspect it will be released Monday soon after close of trading.
