Though they haven't been confirmed, the art style seems pretty similar to the supporting artwork that we saw before the original title was released. A sequel to Heavenly Sword has been talked about for years; the game was originally planned as being the first in a trilogy, but since Ninja Theory has recently focused on multi-platform development, it seems increasingly unlikely that a follow-up to the PS3 exclusive will happen.
Ninja Theory is currently working on the Devil May Cry reboot, DmC, which is due out on January 15, 2013. They previously worked on Enslaved: Odyssey to the West, the art style of which was very clearly inspired by Heavenly Sword.
