It was in Terzake on Canvas.
The footage can be found here
click on it!!
and be as stunned as I was (and Hurri too
EDIT: terzake is something like the news and the topic is investing in flemish developers.
They interviewed a few people from larian (Swen Vincke, Farhang Namdar (lead designer)) And during the interview they show a little bit of the game.
Some guy with a big sword running around, npcs with white text over them.
so I guess thats the way you can oversee their conversations
And somewhere in there you can see a list that is something like a to do list (for the developers, not for us).
EDIT2: Ok so I found the full link and replaced the bad one above. Enjoy
oh and unlike Hurry said, the footage is available right away, the minute they broadcast it you can watch it online. Unless you were talking about something else ? (And I think, it will only be online for a couple of days)
