Full metal alchemist was spedrun on brotherhood but really only the beginning. So i dont see it approached in the same manner, also because the world of both (fma and and wolf)are much too different. Maybe they will do it like fruits basket. Hopefully bring in the og cast(i havent read up on it to see this being true or not) and continue it like that. However the approach, its got enough attention to get the previous fans talking about it and new people interested in it. So whatever is being done, its at least working to some degree. Plus to the new crowds, its different in a sense to what has been told recently.
