Heavenly Sword is a trilogy -- second story already complete
If you're curious, it's right around the 11:00 mark in the interview (the last minute of it, really). Also mentioned were downloadable content possibilities (based on what players would like to see added) and support for Home. The sequel depends on the original game being treated to a successful run, so let's all pitch in and make sure Heavenly Sword makes it through the trilogy loop.
