release dates?

I have read in some threads that PE is fixing to come out with a sub to go with the ref series drivers. Does anyone know a time frame, or a specific date?
Also, does anyone know when the new AE subs are going to come out? Are the cones going to be polished aluminum again? How much of the lambda motor technology are we going to see incorporated into these subs?
How do you think these drivers will compare? (PE ref, new AE, lambda)
One final question, how exactly does one go about buying a lambda driver these days? I know you have to buy it from some guy, but thats about all I could find from searching.
