Yea, I hate it when anime does that. But most of the time its because the anime didn't get good ratings (though I'm sure Pandora Hearts did well) or because the company was going under (Which is what happened with Gangsta)

That or it could be like with Fruits Basket and the Mangaka was so displeased with the animators, that they refuse to allow more anime to be made.... >-> apparently Furuba's artist got pissed over Kyo's bracelet.. the animators changed the color it was suppose to be or something.
