A few days ago
I asked for some info regarding the remaining KS materials in another thread.
We have been told several times that these would be made available before the CM launches, so the issue with Paizo being first out of the gate doesn't apply. Plainly the mechanism for delivery exists, as other free materials are available. These are not Paizo materials, so the API issues don't apply.
But my query in the thread linked above has been met with dead silence from LW. Possibly I asked too nicely? This thread started out with (tongue in cheek) semi-snide sarcasm and got near immediate response...
