Deus Ex: Human Revolution Will Not Have Dynamic Difficulty

The latest issue of PC Gamer has a preview on Deus Ex: Human Revolution. Their website offers one tidbit for it, in which a response is given to Eidos Marketing and Communications Director Matt Birch's claim that Deux Ex: Human Revolution would have dynamic difficulty that would scale (based on how much experience points you have, and how you level up within the game.)
(I don't know who said that,) said Anfossi of Birch's comments, (but that person was either drunk or doesn't work here.) He made it very clear: (No. We have three difficulty settings: Easy, Normal and Hard. There's no adaptation of the difficulty at all, we don't have anything like that.)
