Rumor has it, titanium Commanders will be offered soon. Possibly sometime in the next few months. Price is expected to be in the mid to high $200 range.
To answer your other questions, Emerson says there will be some new production knives coming in the near future. It is hard to say if he will borrow from his hand mades or not. the production knives are a good mix. The Raven did not have a handmade predecessor, The SpecWar did not have a handmade predecessor at least not a folder. The CQC-7 is self explanatory, the Commander came from the ES-1. La Griffe came from Fred Perrin hand mades. I am thinking the next new production will be a new or unknown design. We shall see.
Emerson seems to be very fond of ATS-34 and it's American counterpart. I don't think he will change steel in the near future. He has been using the same steel for a long time.
Can anyone else correct or fill in any blanks?
