Picked up a Google Pixel 32GB from the gray market last week. Prices are still quite high. I am told the source is the India market, and the packaging and included AC Adapter seems to confirm this.
I can confirm Google Photos recognizes the Pixel and says photos and videos will be backed up at original quality. I wasn't sure it would since it's been found some features like Support don't work outside the launch countries.
I'm using the phone on Smart network, and here is the major disappointment: LTE Data flat out does not seem to work, at least in the areas where I find myself. I've set the phone to prefer 3G networks, but missing LTE speeds and coverage that I got out of the 5X (such as it is for Smart).
Finding a case for it in stores has been pretty much impossible (Spigen are only selling the XL cases), so I ended up ordering from Lazada where I found one sold by Ringke Direct.
