Which reminds me, why the HELL is Funi's Mustang going to voice Al now? If anything, he should be taking on the role of Armstrong in a live-action movie. I'm serious, in the video where he announces his role as Zoro, I was mistaken at first to think he was Armstrong because he was large, bald, and beefy. For a full five minutes afterward, I even confused the names Mustang and Armstrong because of it.
Ummm… where to start, lol.
Travis Willingham voices Mustang, as well as Ace. Chris Sabat is the voice for Armstrong/Zoro.
Now that said, funimation as not made a casting choice for the next Al yet. That specific question was asked to Travis at anime con and he responded "We haven't figured out who will play Al; we'll probably hold auditions with kids again. Aaron can't do the voice anymore, we've already decided it won't be him."
The thing about Sabat playing Al was a joke :P
