Google’s Nexus line of phones have traditionally offered a great value on new hardware and that’s exactly what the Nexus 5 appears to be, according to the Google Play store. In what can only be considered an accidental reveal, the Nexus 5 is showing up on the Google Play Store along side the Nexus 7 and 10.
Not much can be noted from the image but it does look like for $349 you can get a Nexus 5, in black, with 16GB of memory. The memory is noted from the URL slug.
Seeing as the Nexus 5 is already in the store, it would makes sense that Google will be announcing the phone very soon, likely tomorrow.
[Update] Looks like the phone may have been pulled already, thankfully, we got a screenshot of the device.
