Everything points to a “yes”. The codename, which is Mako, is a type of shark, and all Nexus devices have fishy codenames. Further more, we’ve never seen this device before, and the rest of the tech press is enamored by it as well. A gallery of extra pics can be seen at the xda-developers, who found the pics.
With specs like an LG Optimus G, plus the latest version of Android, it would make for an interesting package. What do you think?
