During their Anime Expo panel, Crunchyroll announced that they had acquired the streaming rights to the critically acclaimed anime from 2010, Fullmetal Alchemist: Brotherhood, both the English Dub and the Japanese Sub. No announcement yet, on when the series will be going live on the site, nor what territories it will be viewable to, as well as whether they’ll release the series in one drop or in multi-episode releases, but it will be releasing during the summer.
