Was looking at the credits on TenchiMuyo4th.com (http://tenchimuyo4th.com/contents/stacast/index.html) and noticed MK isn't the character designer this time around, instead as General Director. Heard this a while back that Takeshi Oda (http://www.animenewsnetwork.com/encyclopedia/people.php?id=49909) is doing that role.
Other than that one pic and character designs, I haven't seen anything from OAV4 that looks drastically different than MK art, although obviously not identical. I wonder how this will bode for the series and why this is the case?
I wonder how MK will do in General Direction, I see some weakness in storytelling possible although it could be that he improved with his GXP novels. It's obvious this series could be only 4 eps, or longer if successful, it's a very different environment now than anime of the 90s.
