Ok this is pure speculation and me half believing it half admiting that I am crazy...
But Peter M. is famous by his talk on emotions. Now, is it possible that the Dimitri project is related to AI actually feeling emotions, not just portraying or acting emotions?! I mean, that would be something everybody believed to be impossible and something that when released, would feature in magazine covers.
Also Dimitri, very much like B&W would be more of a tech game. One where they explore the possibilities of a certain engine rather than a compeling gamestory (I really like B&W, don't take me wrong).
Anyway my compliments to Mort and Giffdud (checking your thread next) this is, if anything else very entertaining.
