dang, that blows. Demon's Souls was critically acclaimed, so I feel like it makes perfect sense for Sony to have them work on another Souls game after that. maybe even a Demon's Souls 2, if they feel like doing a Bloodborne 2 wouldn't be right. but that goes back to what I was saying before with FromSoftware still just cranking out similar games. Sony could just go to them for another deal to make a sequel.
It would be expensive, but seeing how Souls games have become mainstream, the likelihood of Bloodborne 2 outselling the first game should be much higher.
