Are there еще Narnia Фильмы to come?

I know Voyage of teh Dawn Treader is about to come out, but after it will there be other Narnia movies? Will they do Silver Chair and the Last Battle? And does anyone know if they're planning to go back and do Magician's Nephew and Horse and His Boy?

I thought I read somewhere that the Фильмы weren't making enough money and they were going to stop making them :(
