it has been in development for 2 years now if i'm not mistaken, and i haven't heard anything about it for a while. in the team henshin twitter they have been posting some klonoa things but nothing about the anime, is it still in development? if so, are there any release dates or something?
Two years come the 28th of October.
Also, I wouldn't worry much about it.
Film making (animated especially) can be a while.
You gotta have the artists, the art director, the voice talents, the voice director, the main director, the writer(s), etc.
Stuff like that takes a while.
