@Tenzen - What X-men thing are you talking about? That's odd that an X-men cartoon would be made in Japanese, but if it's true, I guess it would be ok for AF to be Japanese made. But it wouldn't have to be, because there are anime-style cartoons made in the US (or UK, Idk).
It is true curently there are four colaboration between Marvel (real authors are in too)and Madhause studio which are (chronologicaly):
Iron man, Wolverine, X men, and now is aired third episode of Blade. All are voiced by japanese Seyuu (voice actors), voices remain same (cameos staring) though every show have diferent character design. All also more or less acurately describe "real" in marvel events that taked place in japan (I did little research but not enough to say how much acurate they are). Best IMO are so far X men.
It doesn't seem there are plans for export (and dub)for now.
And thank you for admiting that posibility, Personaly I found be Anime most suited for AF action and dialogs).
