Whether Mac players didn’t ask for this or not, the recently released RPG is coming to the platform this Winter at the earliest, or possibly 2012, as a solid release date hasn’t been announced yet. Better not buy it in Gamestop though.
Handling the port are Feral Interactive, who seem to have quite a track history of porting PC games to Mac, having previously been responsible for Mac ports of Bioshock and Borderlands amongst others.
Deus Ex: Human Revolution was released last month and had quite a positive reception all around, with many agreeing that it is a worthy sequel to the original Deus Ex. No pricing or system requirements have been announced yet but I imagine you’ll probably need a Mac or Macbook Pro of some sort. Whether you’ll wait the extra time for the port when you can pick it up on PC, Xbox 360 or Playstation 3 now is another thing.
