Iphone 5 Liquid metal concept

This is a beautiful concept for the next gen. Iphone.  French designer Antoine Brieux design this new Iphone. It’s fanciful stuff, of course, featuring a Liquid Metal casing, but what I find most interesting is this idea that the home button could be replaced with a “virtual home button” that displays on a larger 4.5-inch widescreen display.
Since there is not any physical button present then interface for the hpone will be great in landscape view because this virtual button can hide it self when its not required. This phone could have apple A6 chip in it.

Its just an concept and its not sure that it could be next Iphone because its home button it the thing which makes it different from other smartphones in the market.
Here are some more photos of the Iphone 5.
