Considering they had titbits of information and even characters from the first game (Tracer Tong) in Human Revolution I'll be surprised if they don't mention the Dentons. I am expecting atleast JC to be mentioned or even have a story significance considering it's set the same year he is born..that is no coincidence.
can you imagine now seeing bob page not just in the darkened cutscenes from hr but in game and him mentioning the d project so cool
anyway i expect the story to be great. i loved the last section of hr with panchea and the hyron project. best part of the game for me. especially how the missing link expanded on all that.
