This won't bother anyone, everyone has always praised MGS as being a playable movie and its the most repeated source of praise Kojima has offered this game. Unless the game is utter trash none of this will matter and the game will most likely become an endearing addition to the gaming world due to its uniqueness in this regard.
Whether this will be a good game or not won't be known until 6 months after it comes out at least, by then the game and its flavor will of had a chance to sink in. With all the anticipation and the conflicting idealogies between fans of what makes an MGS game an MGS game, this could be the worse game ever made and it would get 10/10 reviews and fan praise sung from mountain tops for all to hear. That said I see no reason to think it won't be a great game, but none the less MGS2 is proof that not all that glitters is gold.
Be cautious friends, high expectations have a bad habbit of biting people in the ass this generation.
