I usually consider wikipedia in Japanese is a very reliable source for anime news..because it has much more contents than the english's counterpart in regard with anime news or info
So I did a quick check on wikipedia
http://ja.wikipedia.org/wiki/%E5%A4%...9C%A8%E5%AF%9B
it does say he helps writing a script for macross F.....
But then again, it's wikipedia
The simplest solution is, someone emails him and asks him what is going on XD
