Hi puschnik and welcome to MySwissAlps!
Yes, schedules aren't released yet for beyond December 9 (and typically you can't book more than 90 days before travel).
You should find them available by the 2nd or 3rd week of October - you shouldn't have any trouble making reservations - here- for that time of year.
