And I like this promo image a lot.
The new Blade is a high school girl named Fallon Grey who also happens to be the daughter of original Blade. You know, the one Wesley Snipes played in three movies? He's in the series too, but I'm assuming that from the above picture, she's probably going to get more of the attention. Comic Book Resources has an interview with Tim Seeley, the writer of the new series. Worth reading.
