As long as it isn't like Deus Ex 2: invisible war. That game killed its own ambience not even 2 minutes in with the lines:
"Oh no! I just saw someone get killed"
<another not even worst voiceactor ever playing a character that wasn't with me at the time>
"Nah, that's nothing, they did that too when I was in training."
I am very cautious being optimistic, because although a lot sounds to be as good or better than DE1, the interface I've seen in the teasers is the same as in DE2. I hated that interface and it's in DE3, ooh boy.
So, as I said, I am VERY cautiously anticipating this game. I like the 25 hours news, but I do hope that they haven't watched too much to DE2.
