Well, Winter Sonata aired yesterday in Japan, and there were only 3 episode finished and ready to air at that time. I would say that is really far behind. Of course, they are expecting to have 5 now, but I wouldn’t count on it. I’m starting to wonder if they will just end up having to wait till later to show it, because this isn’t a good thing for them. Rushing through an anime causes some rather bad problems sometimes, just look at Akikan.
Though, they themselves say that it might be because they changed directors. They also say it won’t be delayed, meaning there is a good chance it will.
