'Ergo Proxy' is licensed by GENEON USA, with the first DVD coming out in December. Details are in the thread announcing the official website... Ergo Proxy Website is Up (well sort of...)
If you want suggestions on other Dark anime series, there's 'Speed Grapher', which we have a current thread topic going here... Speedgrapher A.k.a. Speed Grapher
There's also the award winning series 'Gankutsuou' the Sci-Fi remake of 'The Count of Monte Cristo'... GANKUTSUOU--THE COUNT OF MONTE CRISTO: GENEON USA Website
That should be enough suggestions to get this thread going... I'll leave it to other members to mention the various 'vampire' genere and 'cyberpunk' genre series....
