As I said in another thread, I think Demon's Souls and LoD are off the table. They said it was a big one and that millions would be looking forward to it. To me, that suggests the size of the IP and how many it's sold, either one game or the series. Neither Demon's Souls or LoD have sold enough for millions to be waiting for it.
Demon souls sold around 1.7m units, but it was the beginning of the souls franchise. The Dark Souls series has passed 25m sold, it's not unreasonable to think that "millions" would look forward to a Demon Souls remake, even if the original "only" sold 1.7m.
