I was channel surfing tonight and came across a show called GameHead on Spike TV. Anyways I only caught the last 5 minutes of the show but they were doing an indepth interview with the creators of Drake's Fortune. There were pictures and discussion about things that haven't been disclosed on the internet (at least I never came across what they were discussing). Anyways they said they're going to post the episode tomorrow at gamehead.spiketv.com, so check it out :)
ps. They also showed an exclusive trailer for Call of Duty 4 (well half the trailer), apparently the entire trailer will be available tomorrow on www.gametrailers.com.
