Wolverine:Iron Man:Wolverine and Iron Man are getting animes. You may be thinking to yourself "how is this any different from The Animatrix or that Batman one," well the difference is that these are being developed as 12-episode series for Japan instead of as Direct-To-DVD features. Is this a good thing? Who knows

The animation is being done by Madhouse but it is mostly being written by Warren Ellis. These two animes are set to premier in Japan for the Spring 2010 anime season.
There are two more Marvel animes in the works, but they haven't been announced yet. Bets are that one of them is not going to be Captain America in WW2 beating up Japs.
imo the animation from the above trailers looks pretty good, but I wish the characters didn't look so tall and thin (especially Wolverine, whose claws also look like they're coming out of his palms or something). Wolverine fighting ninjas in Japan is a pretty standard thing for him, but Iron Man fighting caped pirates is pretty weird.
