It's really hard to imagine these characters from FFVII to have voices. Maybe it is just because the game came out so long ago, that the technology for something like this or similar (i.e. FFX) wasn't even comprahensable on an RPG. Or at least, not for me.

I always thought of Cid to have some hard-arse texan accent and for Red XIII and Barret to have rough voices. That's all, and it was mainly just because of their script in FFVII.

I'm sure they will do a good job with this, though.
