I wonder if Canon has given up on the DO design; also curious how long they spent working on the 400 and 70-300 designs prior to release. Hum. Oh well would be nice to see something new on the optical front.

Canon has filed a number of new patent applications for new DO lens designs. So, who knows, we may see a few more in the next few years?
