If the above image is to be believed, this is what the Motorola Shamu or the Nexus 6, could look like at its time of launch. The smartphone is placed next to an LG G3 so that viewers get an idea of what kind of size they should expect.
The image was published by PhoneArena, which added that the "exact origins of the photo are a bit hard to track, but it seems that it was first posted by a commentator in response to a couple of articles found at Android Police and Droid-life."
The person who posted the image apparently said that the Motorola Shamu will most probably be heading to Verizon Wireless and will also be sold unlocked as well.
To understand how big the Nexus 6 will actually be, compare it with the LG G3, which by itself is a rather sizeable smartphone thanks to its 5.5in display. Yesterday, 9to5Mac came out with an in-house mock up of the Nexus 6 and revealed that the smartphone will be a larger version of the new Moto X (2014). Read more about that here.
As for its specs, rumours have it that the smartphone could feature a 1440 x 2560 (Quad HD) pixel resolution, a quad-core Snapdragon 805 processor, 3 GB of RAM, a 12 MP (or 13 MP) rear camera with 4K video recording and more.
