Deus Ex: Human Revolution Interview

In this conversation between Siliconera and Deus Ex: Human Revolution creative director Jean-François Dugas, we learn that there are currently no plans to release modding tools for the PC version, that seemingly small decisions will have a butterfly effect, and more. On the linear nature of the game's hubs:
We've seen Adam [Jensen] go from China to Detroit, but we haven't really seen how Adam gets from China to Detroit. How do you move between these locales? I'm assuming Adam's going to travel to many countries.

It's true in the story, you're told that you're going somewhere, so you'll just get into your special aircraft and then we load to the next location. So, it's going to be as simple as that.

With the aircraft, will you be able to go back to explore different parts?

The game structure is quite linear in the sense that the story tells you that you're in Detroit, and now you're in China or you're wherever you are. As long as you're where you are, you can explore and do a lot of things, but it's not like a central hub where I decide (Oh, now I go to Detroit.) It's linear, it's told in a linear fashion.
