I'm pretty sure the plan is to release what has been done. I don't know if Aegehn is still on the case with that or if he's given up - he's the one in charge of that side of things. We have the entire main story done, but I highly doubt the entire game will be translated.
By main story you mean ALL story scripts have been transalated to english? What about the Movies? Also any progress on the actual Side missions(if there are any side missions)
