Relevant information from the recent press conference:
The PlayStation 3 will require the hard drive peripheral and the unit will ship with the system right out of the box. In total, it will be 60GB big, be completely upgradeable, and support Linux OS. Additionally, the peripheral will act as a home server and allow users to store various forms of media to be pulled up elsewhere.
All PlayStation 3 games will ship on Blu-ray to help prevent piracy. In other words, no "cheap" DVD releases; Blu-ray only. Of course, it'll still play PS2 and movies on DVD, but all PS3 releases will be on Blu-ray. The company expects initial BD-ROM production to reach 2.5 million in Japan and Europe and 5 million in the US.
The PlayStation 3 will be launching in early November worldwide for the North American, Asian, and European territories. Once released, Sony will unleash one million units per month with a total of six million units in 2006 alone. Production numbers are higher for PS1 and PS2 in their initial years.
The PlayStation 3 will include a "next-generation" HDMI port. (possibly meaning HDMI 1.3??)
