The Inq saw a nice physics demo at the IDF and published some screenshots.
However, looks aren't the only thing this game has to offer. Remedy started to create the game actively using HDR, offering different lighting effects and implementing them inside the game environment, featuring changes between day and night, while weather effects combined with physics were really impressive.
Regarding physics, Remedy showed us a demonstration of a tornado which was breath-taking. In the next three shots, you can see what happens with the house once tornado hits.
