Last week the 32GB Nexus 6P returned to the Play Store. This week, the device is almost fully back in stock. All three size options are once again available for purchase but the colour options still vary depending on the size.
As of this writing, the 32GB is only available in Graphite. The 64GB is available in both Aluminum and Graphite and the 128GB only available in Graphite. Shipping time is a little longer right now with devices not slated to leave the warehouse until November 12.
