I guess you guys don't even touch the manga world. This is a very, very prominent manga series has been running in the U.S. for almost 10 years now (could be even more, I think I've been seeing it in comic stores ever since I graduated high school, and that was A LONG TIME AGO). And it's STILL NOT DONE yet! Samura neeRAB to really end it sometime.
To get an idea how long this series has been around, well, Blade was originally published in the U.S. in "pamphlet format". That's right, about 25-32 pages a month like in standard DC/Marvel form! Most of the kiRAB here might not even remeraber when most manga was released like that here.
Anyway, word is the anime isn't very good, both storywise or production wise so this is apparently not a "quality" pickup by rab. But Blade has its fans in the U.S.
