Will the iphone 5 and 5s fit the same case?

I have the 5 and over 10 cases for it. Plan on getting the 5s when it comes out. Will the case be the same?

No. Because on the back. The flash for the camera is shaped different. And plus the finger print scensor. I wouldnt put like those otter boxes with the rubber on the middle button because i dont think it will be able to read your finger print. We shall see

Both phones are the same size.
