I don't know if this still holds true but in the past I've noticed JB usually posts a small blurb on their homepage on the Friday before publication, that on Noon Sunday - whatever the date, they will be posting their new extended fare schedules and prices.
It seems like we should be seeing something soon since it's been a while since the last posting.
