The availability of them in the NE USA seems decent. Not walk in the store and grab one, but I placed an order for a Space Gray 12.9 512GB and a Space Grey 12.9 512GB on Saturday last week and they arrived yesterday (Tuesday). Our iPads came from a Verizon warehouse in Pennsylvania. Ours are the cellular model from Verizon. It seems like Verizon has a lot of 512GB 12.9 iPad Pros but is short in supply of the 64 and 256GB models and the 10.5 iPad Pro is back ordered. Hopefully this helps anyone looking for a iPad Pro in this region.
