We have some images of third party case designs which are supposedly for the next generation LG-Made Google Nexus 5 for 2015. What's intriguing about these cases is that they would suggest the design of the Nexus 5 will change substantially.
Based upon the placement of the holes, the rear camera will move to the center of the device. We also have a larger spot for the rear flash which is likely the rectangular hole. One of the circular openings is probably for the camera assembly, while the other is possibly a fingerprint sensor.
We can also see the phone's physical button’s positioning (in some of the images in the thread below). This includes the headphone jack as well as the speaker and charging port. This is so dramatically different than the previous generation of the Nexus 5, we wonder if this is for a different device. Such is the nature of unconfirmed leaks...
