It looks like Marvel may finally be taking a hint from DC in the animation department, at least based on the drawing style depicted in the poster (click on the image for a larger view).
Up until recently the animation style of Marvel Universe characters brought to the small screen has been shall we say, not that great. To their credit they did come out with that brief CGI Spidey show on MTV a while back, which while different, was kind of creepy looking. They also tried for a more stylized look with the new Fantastic Four animated series, but personally I find it offensive to see the venerable FF drawn in an overtly anime style.
However I'm liking what I see in this pic and will tune in to see how it turns out.
