Going by experience, I'd guess that the defense has a solid claim in re discovery, i.e., the prosecutor failed to turnover doc's that the defense had every right to; but which the prosecution is used to receiving judgments that the withholding thereof was inadvertent and was not a "critical" error.
Of course, this case will be different.
In this (unusual) case, the defense will be granted the discovery that was their right. Meanwhile, during the drawn-out procedure, they will let the key witness against them go without a good nights sleep.
It's something coming from the defense I would bet and the usual stalling tactics. For Peterson it's no skin off his back since an air-conditioned courtroom sure beats sitting in a prison cell all day, especially since his days may be numbered anyway.
