The White March gameplay
 

Twitch recording (Dozale posted the link elsewhere)

Reminds me of Icewind Dale (with reasons going by the interview)

KS backers who backed to have the expansion gets both part 1 and part 2 (once it get released). The expac content open up after you reach the Stronghold in the game (you can scale the content of the expac if you are too high level for it).

What is new in the expac:
- new areas
- new companions
- party AI
- multi-class talents
- updated UI elements
- new enemy types
- new cap of 14 (if I heard that properly)

I want more details on updated UI elements :D
