According to Eyes on FF, the Japanese voice actor playing Cloud is Takahiro Sakurai. He did Cloud's voice for Kingdom Hearts, as well as playing Sion Barzhad in The Bouncer. He's also been in a lot of anime, but most of it seems to be pretty crappy stuff...Digimon, etc. On a good note (in my opinion) perhaps this means Square will get the Amerian voice actor of Cloud from Kingdom Hearts for the English dub...
