There's not much here, but I thought some people might still be interested.

"We don't want to be seen as a one trick pony."
Eidos Montreal boss Stephane D'Astous has worked up the courage to talk about Thief 4 to us again. Well, he's worked up the courage to talk about what the game has in common with the studio's debut effort, Deus Ex: Human Revolution.
"The success of Deus Ex put two things in perspective for us," D'Astous reflects in an interview published in issue 87, out on Wednesday. "Our second game needs to be as good or better than Deus Ex, and it gave a lot of credibility to the studio. Putting a successful game under your belt brings more confidence and credibility, and less red tape. We don't want to be seen as a one trick pony."
Thief 4 runs on Unreal Engine, features some sort of online functionality and will bring "more than just stealth". Eidos Montreal is taking the same no-holds-barred approach to gameplay it took with Human Revolution, but is "definitely a different approach, a different play style."
"In Deus Ex, we really wanted to give different options in how to play, and we will want to bring a certain level of that to Thief," D'Astous went on. "I think if people spend $60 on a game, they want more than corridor shoot shoot, corridor shoot shot. People are asking for a little more, so give them the choice of how they want to play."
There you go. Exhaustive. Pick up a copy of issue 87 for a fuller discussion of Thief 4, Eidos Montreal and Square Enix action projects at large.
