Official movie website uploaded the 4th trailer!
I'm so nervous now...the movie seems to be going off to the bad end now..........
But I'm happy the brother will at least MEET each other...Roy, Riza, Armstrong(see what he doesXD) and Winry are also in the trailer, including Female!Dietrich Eckart and Noa.
Nervous at the end, when Al shouts 'Nii-san!' nearly crying while being carried away by some millatary person...
Anyone care to translate?

NOTE TO ONES WHO HAVEN'T FINISHED THE SERIES:
