An 1080p display and zippy A15 CPU's are no-brainer's, but here are some less obvious but still importantthings. 1. No front hardware buttons, there's no need for them and they hinder innovation. 2. A nice design that matches its high-end statues. 3. Revised designs for touchwiz icons. 4. A dark black front design, to fit in with the Amoled display (as in the Galaxy S2).
