The Cult of Rapture relates a post from the 2K forums where Ken Levine suggests avoiding the forums if you are picking up BioShock this week, as there are plot points that will probably be spoiled as a result. An earlier post offers the news that the eagerly awaited BioShock demo is due for release at 7:00 p.m. Eastern time today:

The wait is nearly over. At 7 PM EST the BioShock PC demo will go live for you to enjoy. We will have exclusive pre-loading at Fileplanet. Set your watches for 7 o'clock!

IMPORTANT: Please be sure to download the latest drivers from ATI and Nvidia that will be available Monday for best performance with your video cards.
