Demon's Souls servers being shut down

It was recently announced that the servers for Demon's Souls will be shut down next year. March 2011 is the scheduled time but it's kind of weird. Demon's Souls was an unexpected hit with tons of people still playing. The EULA that is in the game says they will support the servers for at least 6 months then they have the right to switch them off if they want. It's been nine months since the game came out and looks like we have 8 more months with the servers up. But why shut them down when you still have a lot of people still playing? The Demon's Souls board over on Gamefaqs is still in the top ten as of this writing it's number 6. That shows a pretty good fan base just on Gamfaqs alone. I'm thinking this announcement is leading up to them revealing the rumored Demon's Souls sequel and I surely hope that happens. I'm going to guess we'll hear about a follow up closer to the shut down of the servers or maybe they have something ready for release around that time. That's would be pretty sweet.
