Joaquin Phoenix To Play The Next HULK?

So it's sadly been confirmed by Marvel Studios, that 2008's "The Incredible Hulk" star, Edward Norton, will no longer play the role when the character is re-introduced in 2012's "The Avengers". It was confirmed also by Norton earlier yesterday morning.
So now the rumors have begun on who will be the next "HULK" in future films. One big main casting rumor is that actor, Joaquin Phoenix is in talks to taking on the role in "The Avengers" and in future "HULK" movies.
Now, Marvel did announce that they are intending to cast an unknown actor for the role. Now Joaquin Phoenix aint unknown at all. Choosing Phoenix wouldn't be the worst choice in the world. But I love Edward Norton and I'd rather see him return than have someone else. It looks like the "HULK" franchise will end up like "The Punisher" franchise, keeping recasting the lead role of "The Punisher". Not the best move really!
