If the rumors are true, then this might be the look of the next Apple iPhone or iPhone 6 (if Apple choose to continue the numbering). It looks slimmer, has almost zero bezel and seems to have a bigger screen.
Actually, I think this is actually not bad looking. The current iPhone 5s is already thin. This seems thinner. And this is my first time to see a screen so close to the edge (almost zero bezel). I would love to see all phones in future to sports minimum bezel.
Here are some more pictures
There is no way to confirm if these casing are genuine or not.
