Anything on the sequel?

Did anyone hear anything on the sequel. The Fighter came out 3 years ago. I can't wait for The Fighter 2. I can't wait to see his battles with Arturo Gatti brought to the big screen. Gatti himself was like an underdog Rocky like fighter that fought with a lot of heart and had his share of wars. A lot of the movie should feature Gatti and his life. It should also go a little bit into the wars he fought even before taking on Micky. It's going to be interesting. During the first fight, the crowd was cheering a lot for Gatti. All were great close brawls, but Gatti ultimately took 2 out of 3 from the trilogy. I can't wait for this movie. I wonder who will play Gatti. I don't care if it's an unknown. As long as he looks like Gatti and can act.
