Yeah, I think they have side stepped those expectations in the last week or too with enough influencers and what not, I don't think many will be disappointed at least for it not being a souls game. Probably safe to expect a good few people getting pussed off and bombing it.
Oh, I do not believe people will be pissed its not a souls game as it does carry over some of the mechanics. Instead, gameplay wise the combat is definitely different. From a few souls players who were playing this game, they state the combat is harder which for the casual player probably will make them give up on the first boss. I believe its level of difficulty for the true souls player will present a challenge they expect.
