Is this the new iphone 5?

This picture has hit in the internet claiming to be a case layout for the new yet to be release iPhone 5

It;'s showing a larger home button, most likely it will be a gesture area as opposed to the button that we are used to. This is typical fare for pre iphone releases. I doubt we will get as lucky and find an actual prototype left in a bar like last year. Time will tell of course.
