Pawns generally come out after the last adventure. I seem to recall comments from staff about needing to see what new art is required for pawns for characters/monsters not illustrated in the adventures as being a factor.
The dice are a third party (Q-Workshop) product, and can take a long time to be available if there's an issue somewhere in production. The extreme case for dice was Jade Regent, with a four year gap between the last adventure in the path and the dice finally being for sale through Paizo.
