I suppose it might have something to do with Portal not having many open areas, and generally much less stuff moving at once? Anyway, this is what usually happens when a very capable developer makes a game that taxes the hardware, but the job of porting it to another system is given to a much less capable team with less time on their hands. Hope they get it going, as even Playstation owners deserve to experience the genius of the Orange Box. =P
