I was offline for a little while, so I wanted to see if something was released confirming that date. You have been following this very closely, so I thought you might have read something on that point.
I am waiting to hear if he actually announces he will abide by that request. If a motion has been pending for some time (think 4 to 6 months), and usually if a trial is imminent, a judge may offer a date to the parties for purposes of trial preparation. This is a ruling on the motions, and nothing more (in a letter containing the veiled threat of a much more complicated life for all if things do not get done by then - meaning the need to paper the docket with emergency requests). Given the short life span of this federal case, I would be very surprised to see the Judge pin himself down with that date. If he gives such a date, then I expect it would be on 8/19.
