Nexus 5 to come as Nexus 4 (2013) like Google did with Nexus 7, here are the arguments

The leak's Italian sources, however, are slipping the idea that Google might actually name it Nexus 4 (2013), like it did with the Nexus 7 (2013) tablet this year, and could do with the leaked Nexus 10 tablet as well. Their arguments are numerous and sound rather plausible at this stage.

First off, the phone itself says Nexus 4 in the settings, but its keys, frame, display, and other hints aren't of Google's hit phone. There's no faux chrome rim around the sides, so some suggested this is the Galaxy Nexus. The screen's black, however, is not completely dark, indicating an LCD display, and looks way more defined than the AMOLED one on the Galaxy Nexus. The front camera on the left and the earpiece grill on the right jibe with the positions we saw on the leaked photos of what we thought will be called Nexus 5.

The baseband version listed on the phone is an earlier one than what we have now on the Nexus 4, with LTE enabled, whereas Google has it blocked on last year's device. Moreover, the build is listed as "hammerhead", whereas the internal name of the Nexus 4 in that department is "mako". Finally, in the interface part you can see that the phone's gallery and camera apps are different than what we have on the Nexus 4, while the app drawer has 5x4 instead of 5x5 grid. 

All in all, the conclusion from this rather different, yet still named Nexus 4 device the sources have, is that Google might save the Nexus 5 moniker for next year's big Android 5 edition milestone, and simply ship this year's version as Nexus 4 (2013) to go with Android 4.4 KitKat. What do you think - logical explanation or a stretch derived from a prototype?
