It has been hinted at by Activision that Angry Birds will indeed be hitting consoles. Right now it is no more than a tease but Activision are planning on taking the game to consoles, presumably as quickly as possible. There will be an announcement over the next two weeks to confirm this, we will keep you posted!
In May this year, Rovio Mobile told the world that Angry Birds games have been downloaded more than 1 billion times. That and Theme Parks makes me wonder why it hasn't been tossed at consoles sooner!
