There is nothing to split, Demon's Souls ain't Dark Souls. And niche? I disagree. I can totally see it happening. From and Sony maintain a good relationship, I don't think Sony will leave the IP in other hands.

Sony owns the Demons Souls IP. They could force someone to make it for... presumably baby powder and batteries.

Why would someone have a good relationship with someone when they had to create a new game that was very similar to Demon Souls and abandon this amazing world they crafted and try to rebuild a new one. I seriously doubt they just wanted to make a new experience because we have Dark Souls 2 coming out,
and the game is as similar gameplay wise as much as Dead Space 1 to 2, and they both try to capture similar atmospeheres.

That is like me being happy someone burned down my house and I had to build a new one but it never quite felt the same. I have experienced this in Minecraft and my feelings were quite different and same goes for when I did to some friends.

Oh also how about that port to EU and even NA, I bet FromSoftware loved that Sony would not distribute the game there. I know if I was a dev I would be happy if I was denied to release my game in another region. They were treated very well by SOny, like second class citizens. Turns out that bit them in the ass since the game has gained quite the fanbase and allowed them to get a publisher to distribute their games worldwide.

They are better off without Sony and they dont need them to publish their games. Hell they could probably do a kickstarter for a new Dark Souls if they needed to because the fanbase is quite dedicated.

You said it , instead of releasing games on next gen they still hold the game potential for last gen sales. Playing the same game on new consoles is much better experience then last gen because of the controller / No loading / Better performance / fast OS..etc so imagine if they focused on it.

All the multiplatform games releasing ports from last gen to these new consoles so why not doing the same for this awesome game?. It's dumb, New console owners buy anything right now because there are only few good games. They are missing a lot of sales.

I do this in every generation. Why would i go for something worst when i can have better experience ? :)
