Wow...
What a terribly awful comparison. Half of the Crysis 2 shots are concept art by the looks of it and the rest of the shots are of varying quality after being resized for the montage shots...
Really, videogameszone.de are in no position to speak of GFX quality since they can't even control the quality of their website (ie, the horribly compressed (jpeg artifacts) background of their website).
This is a worthless comparison, sorry.
Even though I have a Watch set up in Feedreader for news items like this, I don't actually don't like reading about this game. Not because of spoilers and such, but because I'm not playing it now!!!
Come on Deus Ex, you can do it!
