While we have been hearing that Konami was working on a new Castlevania title, it is only now that we know for sure that the game is Castlevania: Lords of the Shadow 2.
A picture of it was tweeted by David Cox of Konami asking if the picture was just that or in-game footage. The off-screen image, despite being from an official source, seems to be an odd way to get the message out without a high-resolution image available for folks to get a good look at.
At least it confirms what we have known since last spring.
