I just want to say this, because it's always bothered me. When people say they want "Demon's Souls 2". It just bothers me. I mean, most of the same team worked on Dark Souls. It's clear that at least in gameplay and aesthetics, Dark was a spiritual successor to Demon's.
I feel the same way, and one of the biggest reasons I'm so excited for this game(even though we only seen a couple of blurry screens) is because it doesn't seems to be a direct sequel to Demon's Souls. Don't get me wrong, I love Demon's Souls but I don't want another Souls game that re-uses plot, characters, and setting wholesale from the first game and just ads a new coat of paint like Dark Souls 2 did.
I want Miyazaki to innovate and evolve the Souls formula, and more importantly create new and interesting lore for me to discover.
