Everything said is just a guess.
the video seems to present a something similar to modded game of crysis (blackfire mod for example)
so the release of crysis remastred will make no sense
I agree with Tunsalat I would also prefer that they perfect the old version by developing a new scenario based on the old with more complicated and longer missions to play ... for the graphics there is much more better than most games today .. no need to make it more realistic .. I wish that really .
