Yeah, it really is. Brotherhood is fantastic, but there's still some stuff that it's missing- though not since episode 30.
That episode, the Ishbal flashback, was originally a 170 page epic detailing the war from all angles- Mustang/Hughes/Hawkeye, Scar, Winry's parents, Marcoh and Knox, etc. - but a large portion of the material was removed, and it lacked the sense of chaos that the manga had. Some of the scenes have been added to other episodes and I bet some of the others will be added later, but there's still a lot that will probably never be animated.
Brotherhood is great, but the manga's even better.
