So far, details are extremely sparse on TEW. Outside of the announcement and following images, the only other concrete detail is that it is being helmed by Shinji Mikami. He's better known as the creator of the Resident Evil franchise. The games, not the films. So that can be seen as a plus for the new IP right?
Outside of that all we know is that it will be coming to the PS3, 360, PC, and the 'next gen' consoles sometime in 2014. As we get more info we will update everyone.
