Did anyone play the Shadow Hearts games? What are the chances of there being another?

The Shadow Hearts series (Koudelka, Shadow Hearts, Shadow Hearts: Covenant, Shadow Hearts: From the New World) was a series of RPGs developed by former-Square Enix employees who formed a new development house known as Sacnoth (later changed to Nautilus) in the PS1 era. The bulk of the Shadow Hearts series (save for Koudelka) came out on the PS2, and was known for it's combination of horror, historical fiction, and goofy humor in the time between World War I and World War II.

Anyhow, I loved those games. Any chances of a sequel?
