As you were hopefully already aware, Tim was tasked with giving the keynote address at the GC Developers Conference in Leipzig. So how did the big speech about creativity turn out? Read Gamasutra's snazzy write-up to get the answer to that question.
Update: Gamespot reports that while Schafer didn't give out any details on the new game (which is unsurprising to anyone who's read Schafer's recent statements to Shacknews), he did reveal that the game is scheduled for release some time next year. While this may not satisfy those who recall Psychonauts' projected Spring 2003 release date, it's nonetheless an exciting development.
