Next week's court appearance will be a quick not guilty plea before the trial judge. The court will then pencil in a trial date with the expectation of multiple continuances as SBF has already waived his right to a speedy trial. Next week's plea is just going through the required motions and isn't indicative of SBF's eventual decision to accept a plea deal (if offered) or go to trial.

It's standard for a defendant to enter a plea before the trial judge at his/her/their initial appearance. It's really perfunctory and isn't indicative of future court proceedings - be it a defendant's decision to enter a guilty plea by accepting the government's deal or by going to trial.
