The Matrix prequel

A while ago i read somewhere that warner bros was going to make a prequel to the movies. It's had zak penn attached.But it's been almost 6 months and no new news. Maybe i'm looking in the wrong spot. Anybody read or hear anything about this project?
I'm a massive collector with anything that has to do with the matrix. Is anybody looking forward to it?

I always wanted a 4th matrix movie myself neo would be about 20 years older (not dead) living in machine city. I think keanu said somewhere he would be down playing neo again if the wachowski's where involved. But that's not going to happen they ran out of good idea's a while back.
