It might be useful to mention that APS was designed by Kodak, Fuji, Nikon and a number of other film and camera makers to match digital with film. The frame size of APS is the same as a digital sensor, and APS was designed to record other information bringing it up to the digital standard of exposure and date/time information.
So, other companies also believed that there was some life left in film, not just Kodak. Although we will never know what time line these other companies had.
Now, the crux of the matter is whether the present ApS films contain the information gathering information of APS and whether that is worth anything to anyone today.
