New hardware and software shown in the latest round of Nexus leaks

There's a new batch of Nexus pictures floating around today, showing what's purported to be the Nexus 5 from LG complete with plenty of looks at Android 4.4 KitKat.
The images, taken in Italy and displayed on the Android website, show us a look at the lock screen, the home screen, and a look at the apps of the Nexus 5. Of course, this leads to speculation of exactly what we're seeing, and things like a Tap to Pay mode in the settings and transparent status and navigation bars have a lot of folks excited.
Just as interesting is some testimony from the leaker themselves. The Nexus 5 is said to be fast and smooth, with KitKat being a "lighter" version of the OS that helps in the performance department. Dual stereo speakers are acknowledged in the bottom portion of the device, and the camera is said to provide excellent image stabilization.
Combined with the rumors of a reveal next week, things should start getting exciting right about now. The changes and new hardware look pretty interesting, and we're hoping for an official announcement soon. As things stand now, the only people that really know anything are the people not saying anything.
Hit the break to see the rest of the images, and check out the source link for their take on what they are seeing.
