Japanese video game companies doing most Marvel characters
A Joss Whedon film in the works
Where are the Avengers?
Blade is not a Spider-Man character, that association is only from the 1990's Spider-Man animated series, Blade has next to no ties to Spidey in the comics, I wont go as far as to they never teamed up, they probably did, but not in any memorable way outside Blade's appearances in Spider-Man the animated series. If Blade is tied to any group of Marvel heroes it is Ghost Rider and the Midnight Sons/The Nightstalkers and other Marvel horror characters, not Spidey. As for an Avengers anime, I would not hold your breath, the current Disney Avengers animated series is still running strong and introducing new characters into the series including Spidey and Wolverine.
So far we have Anime of Blade (Spider-Man character)
