After watching the trailer (I can't watch it due to 56k) what is everyone's speculation on the location of Portal? Is it on Earth, or Off-world? Personally, I don't know how a corporation could exist in a Combine-controlled Earth, maybe Portal is set many years post-revolution (after Gordon overthrew Breen), but I doubt it. So, I think it is off-world. Also, I thought the Gamespy article says it takes place in the halflife2 scenario, I'll have to check on that.
