I asked a friend who does review for a small gaming website.
He told me something interesting...
Many reviewers in the industry like to play a majority of the game before they release a review.
My guess is since this game is way longer then normal games (besides skyrim, fallout,witcher)I Don't think we have seen more of the reviews yet...given some people don't have 40+hours yet available to them to finish most of the game.
