Well, rumors a few months ago were that plans had leaked for a third device that would be the spiritual successor to the Nexus line, with stock android at reasonable prices.
We thought we knew, but it seems like a jerk move for Google to make fun of us over our vain hope they'd put out something we wanted.
Also, how does one shop for a phone these days when you want plain old Android and sensible security updates but have other feature concerns as well? I don't want a flagship phone, don't want a giant phablet, and care more about offline GPS performance than data performance...
I am still carrying a Moto G4 Play which I think is borderline too big. It still lasts almost a week on one charge when I take it into the woods in airplane mode and just use the camera app and OSMAnd+ with GPS logging for 3-4 hours per day.
