Question ( becuase I do not KNOW the answer for sure )
Was Ikki Tousen: Great Guardians and/or Ikki Tousen: Xtreme Xecutor already dubbed ??
If not will it be ??
Yes they will contain dubs, since it's coming from Funimation.
It's uncertain how far Media Blasters got with the dubbing on Great Guardians. Considering that the fans didn't like the Dragon Destiny dub much and Funimation has access to a couple of the voice actors from the first season (Hakufu especially), I would say that Funimation will be dubbing (or re-dubbing) these in house.
