Eidos is lying through their teeth - again. The PC demo already has full PhysX capability implemented (paper flutters and the cobwebs bend). The reason for the delay is so that PC piracy doesn't cannibalize their precious console sales.

While I applaud them for what appears to be a very slick port (superior in every way to what I played on my PS3 earlier - Eidos needs to man up and stop jerking their customers around and admit the REAL reason for the "delay".
