Here are some video's I've found:
-HD gameplay from Ubisofts Conference
-Trailer explaining the premise of the story (Also from the conference)
-IGN analysis (Seems to be some misinformation here)
-Interview with developers (IGN)
-Talk about what is The Division (Gamespot)
Also I could have sworn I saw one from Machinima, but can't find it. Maybe it was a live stream.
Edit: Just went up Rev3 interview
