A new iPhone 7 concept video shows how it would look like. They made the design bezel-less that looks cool. The back panel looks quite similar to iPhone 4S, but the edge-to-edge display makes the front look great.
In terms of technical specification, they overkilled some specs. 4.9 inches display for iPhone 7 is acceptable that makes it just 0.2 inches larger than its predecessor. 4.9-inch iPhone 7 would never bring a 4K display.
Physical camera button is not really required. 5-megapixel front camera and 16 megapixel primary camera would do great. You can watch the video to check more detail.
