Edward & Alphonse look awesome, I like how the pair together.
It's interesting to see these at 1/6, but I guess it makes sense in a way. 1/4 may not be feasible as there are so many desirable characters like all the Homunculi, Scar, Izumi, Winry, Roy Mustang and his crew.
Knowing Prime 1 we'll likely see 1/4 or 1/3 down the road.
