No letting you have it! It's a notice of case disposition that says be prepared to pay court costs and fines at this hearing, and it was scheduled very quickly, even before the arraignment (which is normally the time you would formally enter your "not guilty" plea and pick a trial date, and if there are complicated issues to be decided beforehand [i.e. whether a videotape should be sealed, or whether it was legally obtained and/or should be admissible] you aren't picking a trial date 10 days later, unless the Defendant is insisting on a super speedy trial, which I cannot imagine is the case here), so I think Bob Kraft and the prosecutors have reached a plea deal that will be entered on April 9th and put this thing to bed for Kraft. And, if he has decent lawyers (which we all know he does), part of the plea deal is that the videotape will be sealed permanently and the media will not be able to get their hands on it (which is why they are now rushing to object to the Motion to Seal).
Pleading "not guilty" and requesting a jury trial are two things that must be done very early in a case, or they are waived (particularly the jury trial part, although I thought Kraft waived his right to a jury trial(?)). You do it to hold your place and keep all your options open, not because that is how you intend to proceed for the entire case.
