Is there anything special I need to do or know before I download the c3 demo? I don't remember anything special with c2 the c2 demo. At least for console anyways. Also does anyone know when the ps store updates?

The PSN store updates at seemingly different times each week. I remember waiting a full day before being able to download the Bf3 armored Kill map pack, While ME3 retake omega DLC came in the morning... I Guess it depends when Sony hits the big red button
