First of all, the yellow outlines on useable objects reduce the freedom. In the origin DeusEx, everything was move/grab/useable. Having useable objects highlighted is like cutting down the players freedom. BUT, what we have seen in the Walkthrough was just a small area. Since, I am not spoiling myself by reading what they have planned for the final product, I am not sure if there will be large outdoor areas, like the city or area 51 known from the origin game.
