Console wise probably Last of Us since it's ND. But like their games it will most likely be quite linear and corridor like.
When it comes to large environments I think it will be GTAV. Witcher 2 is a high end PC port so I don't think it will look as good as a game designed with console tech in mind.
On PC Metro 2 LL.












but from this list The Last of Us and The Last Guardian.
