Now its getting more exciting.

Let's hope it's not a "feature" that disables all video operation if a lens adapter is detected! ;)

Don't be surprised if that is exactly what happens.

This has obviously wandered into the territory of "Conjecture", but a company updating a product to remove a feature is unusual. I've certainly never heard of that happening.

The closest example I can come up with were the early satellite dishes that gave free HBO, etc., but that was a technological issue, not a marketing one.

Apple does it all the time.

However, I would agree that Canon most likely will not disable anything further. But it wouldn't surprise if they did.
