Goes by the name "Otherland". Sounds like it will be low on the PvP - preview describes as "largley cooperative". Still, they're playing about with some of the typical notions of MMOs apparently - we'll see just how far they deviate from the mainstream.
Also, while the descriptions are quite hacker/cyberspace esque, I don't see the "punk" aspect that properly charaterises cyberpunk at all. Anyone read the novels can confirm/deny that?
