The next Ghibli film is being directed by a newcomer, and I believe Takahata is working on a new film after a pretty long break. So it’s probably not going to be that bad.

And yes it’s true: Miyazaki holds a point where it’s Teacher and students;him being the teacher. He leads on,he stays extra late to finish things. Even if he is hard held,he is genuinely kind unto his staff. He makes them dinner too. They know he is committed. So being Japanese[and knowing him quite well] they only offer help when they think he needs it. Otherwise they stay quiet. Because of the great epicness he is creating.

You don’t know that his death spells the “end” of Ghibli, I bet some senior animators at the studio besides for his son have developed ideas in all those years of monotonously following orders, so a leader could pull forward when he is gone.

Miyazaki once declared he’d be retiring after Mononoke, but somehow he never did, and his iron-fisted rule continues to this day within the studio.
In other studios, the younger people are given a chance to expand and express themselves and develop their own style and skills, but in Studio Ghibli, Miyazaki maintains a Stalin-esque absolute control and crushes any initiative that others might take. The new guys are never given a chance to grow, as the moment Miyazaki sees something he doesn’t like or suit his fancy, he swoops in from behind and fixes it himself (this scene is even featured on the making-of footage on the DVD for Mononoke). And of course, he’s the genius so his way is always indeed better.

As Miyazaki continues to grind with his heels anyone who might succeed him, it’s said that Studio Ghibli will effectively end with Miyazaki’s retirement or death.
Of course there is Goro, but people say unless he evolves pokemon-style into a whole new caliber of a director, he just doesn’t have the gift of his father. Instead, his unique skill seems to be a high level of resistance to his spirit being destroyed by his genius father’s constant berating … which is why they let him try Earthsea, at least.
