A crystal clear 7-minute video of the Nexus 5 (I think we can accept that's going to be the name at this point) was just leaked on the web. It's an older build than the one leaked by TuttoAndroidyesterday, but look - it's the Nexus 5 hardware in the clearest shots we've seen yet!smartphones.sfr.fr appears all over it, so the full credit for this leak goes out to them.
In the video, shot on October 9th if we are to believe the lockscreen, we're obviously looking at a prototype, considering there's no Nexus branding on the back, but one that offers the highest amount of detail to date. It's worth taking a peek at it just to see a close-up of those sexy dual bottom-firing speakers.
As for the build, it's missing some elements we saw recently, like notification bar transparency in the launcher, the camera shortcut on the lockscreen, the new dialer, app drawer, Search app icons, Google Photos (as opposed to Google+ Photos), etc. The build even says KeyLimePie, just like it did in numerous previous leaks, but remember that Google only told its employees the new KitKat name in the beginning of September. Rest assured that it'll change by release time
