just saw this pop up on their blog

Well, this forces the question just how well is the game selling anyways?  We know well enough for a reprint, but given how conservative Atlus generally is, that doesn't imply impressive figures.

I think the game's sold more then they were expecting. I guess word of mouth and out of the blue coverage from websites can get a good but obscure game in alot of people's minds which gives me hope for games' journalism.

 Finally, Famitsu asks the question we all want know “Will there be a sequel?“. Kajii says it’s too early to talk about sequel but he hopes this a “new beginning” between SCEJ and From Software. Miyazaki says the development team is very excited with the idea of sequel since the game was a learning process for them and they kind of know the direction it should go next. Although he isn’t sure if there will be a sequel, he says Demon’s Souls will be an invaluable experience for their new projects.
