This is truly a sad day for movies. I am not even an avid fan but among the best animation movies of the last decades, there are undoubtedly a whole slew of Ghibli movies....
EDIT: Of course, Kotaku has reported about it, I should have known. I don't read them regularly, sorry. That does sound a little less pessimistic, but one way or another, the studio is sure not going tho be the same anymore, afterwards.
