With the Nexus 5 factory image up for download from Google’s website, developers and tinkerers have started getting dirty with it. Someone from XDA downloaded the image and has extracted all the new wallpapers from the GoogleHome APK. 

There are 8 brand new wallpapers in Android 4.4 KitKat, of which 2 are landscape in nature and the rest being abstract.

You can download the above wallpapers at their full resolution by opening them in a new tab, and then use the Save Image as option by right clicking on the image.
