I was tempted by both the 8 and the 6, but now rumors of the pentalens Nokia 10 have surfaced, so I'll hold out for that until the details are released (one of the primary functions of a smartphone is the camera for me).
The 6 seems to be a great choice for getting the most out of your money though.
So what happened was that the official release is in May but one seller (Breed) sold out their inventory ahead of time. In the next two weeks or so we should see it become readily available.It's not in stock, but here is a listing for one with a US warranty.

That's what it said when I ordered mine as well. I received mine from Best Buy yesterday, so it was essentially 1 day shipping.I placed the order yesterday on Amazon. They are saying 3-5 days to ship.
