I wouldn't get your hopes up based on some of the extremely harsh, and nigh on immature previews, Eg Gallahad crying photoshop...Seems a lot of people just really dislike the idea of a linear, cinematic focused game, and a game where innovation in gameplay mechanics was never really a key consideration, rather it was to offer a polished take on what has been done before, but in a unique setting, with more emphasis on characters, narrative, lore, different weapons and gory gunplay.
Personally when I read the reviews I'm going to have to selectively pick through the noise, disregarding the things that don't personally bother me. Eg a lack of innovation, cut scene heavy, narrative, cinematic focus, use of QTE's etc. Really I want to know things like how the gunplay feels, how satisfying the weapons are, is the combat fun, how successful the characters and narrative are, the quality of the sound track, pacing of the game, how good the level and combat design is, the AI, variety in design, how well melee combat and stealth is implemented, how much of a difference the tech and art plays to overall level and of immersion etc.
