From what I can tell from Movie Park Germany's website they changed hands therefore the licensing might have changed as well.
I would have thought that Warner Bro's Movie world would have to stick to Warner Movies or at least the movies which Village Roadshow distribute (Paramount, Warner, Dreamworks & Roadshow). I assume it would be the same for the other parks Village Roadshow own....Seaworld - Happy feet (roadshow), Spongebob (paramount) etc..
Don't get me wrong I really would love for them to update some of the rides but I think it will be one of 'their' movies
