I'm honestly not familiar with Silverlight and JavaFX, but matching AS3's capabilities of OOP... Um, Silverlight and JavaFX have .Net and Java inside, respectively. They don't have to work to "match" OOP, they bring pre-existing OOP to the party. With extensive general-purpose class libraries. I don't know anything about JavaFX, but Silverlight also brings pre-existing XAML, which already has drawing and animation classes. And possibly "loader classes" and "filters", I'm not sure what you mean by those).
