They had the rights to Blade for a few years now and there was talk last year that Marvel & Snipes had some discussions but nothing came about it. I think Marvel going to let the character marinate for a bit. Because basically the live screen version is Wesley Snipes/David Goyer interpretation of the character. Totally different than the comic book version. Even with the success of the movies, Marvel has tried to alter the comics to go closer to the movie version but it hasn't done as well.
Some people say Snipes is too old to play the character Blade again, I disagree, Snipes looks younger than Robert Downey Jr and Don Cheadle they all about the same age. Or they will throw a Michael Jai White's name in the mix, he's around the same age as well.
For many years, Snipes was trying to get Black Panther off the ground, even before he got the part to play Blade. Marvel should acknowledge him for that.
