Google took the wraps off Android 4.4 KitKat on Tuesday, but it appears to have revealed more than it had planned. 9to5Google spotted an unreleased Nexus smartphone in the official video of the unveiling of the Android KitKat statue in Mountain View.

The mystery device, which could be the rumored Nexus 5, appears to be larger than the Nexus 4 and looks to have a similar back to the recently released Nexus 7.
