The spiritual sequel to Demon's Souls, 'Project Dark' recently just got a new trailer and is now officially named Dark Souls.
Apparently they've upped the difficulty a lot, and are doing everything they can to make you die horrible painful deaths.
Also, instead of a hub world, it's apparently going to be a seamless open world. Wonder how that'll affect respawns.
Also the Atlus Demon's Souls servers are staying up til October, and might be pushed back further still.
