Looks good - it's Crysis, it's GOING to look good.
I'm not sure I like the implication on the function of the nanosuits. We knew there had to be some kind of implant that allowed the suit to monitor life functions. But to listen to Prophet, the suit compromises the life functions of the wearer, essentially killing them should they take it off. Which makes it a death sentence to put it on. So where does the suit end and the man begin?
Lastly, this post-human BS is going to get old fast. cybernetics are still in their infancy. We are barely able to replace damaged or missing limbs with barely functional chunks of plastic, much less have fully functional fine manipulation. The idea that in 20 years we could build something that not only doesn't impede the wearer as current armor does, but actually turns them into a Super Soldier ala Captain America is, well I was going to say ludicrous, but since there is a definite possibility that it MIGHT happen, I'll say silly instead.
If you gave the average man on the street the option of replacing parts of his body with better, but robotic parts, 90% of them would turn you down flat.
