I figure the market for PET is huge compared to CTA, and the market for extruded CTA even smaller still. With the rather 'touchy' financial situation at EK, it would probably makes sense to stay with one subtrate only.
The problem is that they can't. Other film bases are subject to light piping and would complicate the amateur film market. Kodak has long warned that when loading films using a polyester base like Estar to do it in subdued light. Polyester base can also damage motion picture cameras and projectors and so cannot be used with them.
