For those of you who are looking for a BioShock demo on the PC, it is in the works and will be out later this month. I'll give you more details about it tomorrow.
re: demo. The demo is great but you can tell where Irrational had to trim back some of the FX to get it running at a solid framerate for the 360. You'll go into a room and things like doors and statues will be very high res but the walls next to them will have this ugly low res texture. If you played Gears of War you know exactly what I mean. The PC version is what I'm getting, I want the full on experience.
