I hope this means that the movie is going more for the horror/suspense genre than the super-hero style.
One can only hope. Blade at his best (as originally intended) is a horror character, and its the very thing that made him distinctive...meaning not being another character molded for / ending up on the typical MCU conveyor belt. He had a presence and world all his own (on the horror side of the publisher), and I would interested in seeing that kind of 70s edge in this new adaptation of the character.
Rumor has it not being an origin story so, again if they stick to comics, Ben is the Thing for the entire film. So a mocap performance. Might be like Ruffalo and the Hulk or might be a Rocket situation with different actors for voice and mocap.
