At first, we were talking about a Nexus 6, a placeholder name that did the job done for the time being, but as more evidence started piling up, we started hearing more about a mysterious Motorola ‘Shamu’, a device uncovered in the Android Open Source Project’s code-base by Android Police at the end of July.
After all those small fish, it was time for something bigger like a whale. It was time to get excited: after all, Shamu is the name of the killer whale that has survived the most in captivity. Most importantly, it is a name of fish, and that is exactly what Google traditionally uses for its Nexus devices: the Nexus 5 was ‘Hammerhead’, the Nexus 4 carried the ‘Mako’ shark codename, and the Galaxy Nexus was developed under the ‘Tuna’ moniker.
