Namco Bandai and From Software are bringing Dark Souls: Prepare to Die Edition to PlayStation 3 and Xbox 360 on October 26, 2012. For players who already have a copy of the game and are simply looking to pick up the new Artorias of the Abyss content, that'll be available as a paid add-on as well.
Alternatively, you can grab the new edition on Steam right now. I'm playing through it and will have more detailed impressions in the near future, but if you own a gamepad (preferably an Xbox 360 controller) and are prepared to use Durante's resolution fix, which is a surprisingly painless process, then go on ahead. Games for Windows Live, while present, doesn't get in your way as much as it could.
Despite not having even the most basic of PC-specific features, the game is absolutely worth playing if this platform is your only option. I just got into Blighttown, and although From Software stated that the frame rate there wouldn't be improved from 360/PS3 (where it was rather terrible), I haven't noticed any dips yet. That alone makes me more than happy to be playing through Dark Souls yet again.
