Let's take a step back and compare it to what we know of dark souls right now, Kay?
1) it's far more action oriented in this trailer, especially in comparison to the first dark souls trailers.
2) none of this seems to be in-game (think of the original dead island trailer)
3) where is the developer info, because none of this is From's style.
4) how does it relate to Dark Souls? Story and setting-wise. Dark Souls was more about the struggle and the loneliness.
Let's not get hyped just yet, mis amigos. I'll reserve judgement for when we receive more information on this.
