If the pic is accurate, and it may not be, then it appears it will have on screen touch buttons instead of the big home button and two on the side in the bezel.
Not a fan of that change in direction.
I wish they would add another programmable button. Touch is great but when you can't see the screen (bright sunlight), the mechanical buttons are your lifeline (and yes, I have configured the existing ones to get as much as is possible out of them).
