I've finally managed to finish the Iron Man, Wolverine, and X-Men anime, and I can tell you right now they are nothing short of awesome. Now all that's left is the Blade anime, though I don't really know if I'll watch it or not, since I'm not really a huge fan of Blade.

Anyways, hell yes, I think another Marvel Anime project would be awesome and kick-ass. Madhouse (or any other animation studio that Marvel Comics decides to collaborate with) could continue the stories presented in the first project (I don't mean to spoil anything, but the ending of the X-Men anime sets the show up for a "second season" of sorts), though I'd really like it if they expanded their views and went with some of Marvel's other potential properties (Deadpool, Punisher, Ghost Rider, Daredevil, Guardians of the Galaxy, Nova Corps, Iron Fist, etc.)

Only seen the Blade anime and loved it, so more the better I guess.
