There's a new reason to think Google might be prepping a new Nexus smartphone—possibly one that might fill the gap left by its just-discontinued Nexus 5.

The latest speculation centers on a Google informational video for its new wireless service, Project Fi (h/t Android Pit). It’s meant to show users how to check their data usage on the new service, which at the moment is only compatible with Nexus 6 smartphones. Despite that, the Nexus 6 is conspicuously absent from the video:

The Nexus 6 on the left has rounded corners and a microphone grill on the bottom that mimics the speaker grill on the top. By contrast, the rendered device on the right is much more angular at the corners and seems to lack a microphone on the front face of the device.

Now, the device on the right isn't anything more than a rendering of a Project Fi-compatible Android device. But its design seems to consciously differ enough from the Nexus 6 to raise some serious questions.

Google's response doesn't exactly settle the question. A company spokesperson told me by email: "These renderings are based on a generic phone modeled off the Nexus 5."
