This is a harsh post from you.This is an embarrassing post from CR guy. I guess not enough people are leaking stories so we have to fill with this nonsense.
Canon is on record as talking proudly as being an "end to end" imaging company, who make everything from their sensors through to printers. They've just had an event in Europe showcasing their sensors, that they're trying to sell to other companies as the best. Further, they're aggressively going after Sony in the mirrorless space.
So yeah, I don't see that happening, ever.
Let us think this through together. Imagine you run a popular rumors website. You hear from a "source" that Canon is considering using a specific Sony sensor in an upcoming APS-C body. So, you think to yourself, "Visitors and members won't find this interesting, and it won't spark any discussion. Don't post." Would that have been your choice?
From this member's point of view, the decision to post was correct.
