Could be a sign, or it could be coincidence.
It also could be a sign that they're loosing sales vs. Nikon in the aps-c segment and want to lower their ef-s system price, the lenses are in production a long time so lowering the price mustn't mean a replacement is due.
but as to whether the people who have any say about product direction read it, your guess is as good as mine.
My guess: No way, the people really deciding about Canon's corp policy would be a handful of Japanese execs who will take advice from their tech, sales/marketing and maybe cps departments, but certainly ignore any Internet buzz.
Some marketing guys will watch these forums to prevent bad press about broken products, but the opinions here on anything are so diverse that a quick poll on cps will be better than reading CR to get the ear to the ground.
