Federal Agent Area 51
Here it is straight from the press release:
Featuring taut action and investigative work, Sherlock Holmes: The Devil’s Daughter, the eighth and latest entry in the franchise, will push your abilities to the limit in a one-of-a-kind interactive experience.
There'll be five new cases and an 'expansive landscape' you can freely roam around. It's also promised that "for the first time in his storied career, Sherlock Holmes’ ruthless logic is overwhelmed by family stories, irresistible emotions and an occult revenge." Probably wishful thinking on my part, but I'm imagining the bit about 'irresistible emotions' as the thing Depression Quest did where options got greyed out as your decisions took effect.
Sherlock Holmes: The Devil’s Daughter is out in Spring 2016.
