Ninja Theory has taken to Twitter to tease an announcement they have planned for tomorrow. It seems that they're announcing a new game rather than additional content for DmC, their latest title.
Tomorrow. Something new to show.

The UK developer has previously created Heavenly Sword for PlayStation 3 and Enslaved: Odyssey to the West for PS3 and Xbox 360. Last month, a direct-to-homevideo movie for Heavenly Sword was announced suggesting Sony hasn't completely forgotten the franchise. Heavenly Sword was released in 2007, early in the PS3's life cycle, and Sony may wise to revive the series for PS4.
It was however reported that Heavenly Sword 2 was cancelled in 2008 after the original failed to match expectations leaving Ninja Theory reportedly "bitter" with Sony. Last year, concept art for the game was revealed.
It's believed that Enslaved did not achieve sufficient sales to warrant a sequel. Of course, Ninja Theory could be set to announce a new IP which will likely make it to next-gen consoles or something connected to the Devil May Cry franchise, a series they rebooted with DmC.
Ninja Theory's website notes that they've moved on from DmC, which has sold 1.15 million units, but something related to the franchise may be in the works.
