If it's good, then it will endure success due to word of mouth. I've actually really excited for this game and the combat looks very brutal! Eradan is my best character because he looks awesome and his background sounds very good too.
You can check out a recent story of War in The North that's been released on the official website:

Oh and check this guy's channel out for unedited gameplay videos:
