Google Store has both 32GB and 128GB models listed - color options include black and silver. Shipments, however, won't begin until next month.
Verizon, on the other hand, has the devices in stock. Blue color option is available as well, but it only comes with 32GB storage for both handsets - the blue Pixel XL, however, will ship November 18 onwards.
