Well, I can't say that I'm too optimistic. One major thing that was very interesting about Garrett's character was that he was aspiring to be nothing more than a thief, but he kept getting dragged into heroics. Thief 2 undermined that a little, Thief 3 a good bit more (partially due to declining writing quality.) It's hard enough to build a character like that once; I really doubt the abilities of people who aren't the original writers to do so again. Particularly when the character is becoming more ninja-like.
That also was unique (and still is) among games - you played a thief, not a sneaky melee fighter with two daggers who picks locks and disarms traps. In the first two games, it was a matter of professional pride to kill no one. The Dishonored influence undermines that; although it had rewards for not killing people, the majority of the abilities were focused around the opposite.
There is also the matter of writing the Hammerites and Pagans. Especially the Pagans, which - with their speech quirks and tree-hugging proclivities - could have easily become a joke instead of the delicately balanced mixture of whimsy and savagery they were in the first two games. Of course, the reboot might cut those factions out (probably to its detriment, since they are a critical part of the setting.)
Edit: And I watched the linked video. I was somewhat heartened by hearing them saying that he wasn't really trying to be a hero.
Then... what the hell?!?! The Joker from the Dark Knight is an inspiration for Garrett?! I honestly have no bloody idea how they drew a connection between the two. And I felt a little more hope die inside.

God forbid! I could not think of a worse game to have QTEs.
I can. "Press X to not be eaten by a grue!"
