I think it will be soon before Nokia officially announced the Nokia Lumia 928. In this picture, you can see a billboard with the Nokia Lumia 928 in it. I used Photoshop to re-adjust the image.
Here, you can see the Verizon logo and the sentence “Nokia Lumia 928 – The Best low-light smartphone camera”. Obviously, Nokia is focusing on the camera of the Lumia 928. Lets hope something interesting will be announced soon.
BTW, here is the original photo from MyNokiaBlog.
