What time is this announcement supposed to be tonight?
5 after never, I'm afraid. I'm calling shenanigans.
Canon hasn't been great about certain design rules, like mixing serifed and non-serifed fonts. The Canon logo itself is serifed, and the R on the R body was serifed as well. But even with all that confusion on Canon bodies, I've never seen them use two non-serifed fonts together, in an attempt to make them look the same. That's just someone goofing with photoshop, not wanting to have to bother to buy a new font.
If Canon's designers stuck that "R5" on the body just like that, than I wouldn't have hopes that other designers didn't forget to put a battery door on the bottom or something equally dumb. This is very unlikely.
If you waste 10 minutes trying to procrastinate from work, as I did, and download the picture and blow it up, you'll see that you can identify where the seams of the layers are where elements were pasted on. Here is a rough line of a color deviance where they added in the bottom right sealed plug and didn't bother taking the green cast from the part they pasted. You can see that also lines up with a pattern deviance in the fake leather along the same seam. The color cast is less apparent in the re-saved JPG below versus my original blow up, but still visible.
You could argue that Canon was being lazy and they designed an example photo rather than photographed an actual example, but then you'd expect the camera itself to be powered inside by a cockroach on a flywheel.
Still, won't prevent me from buying 2 if it turns out to be real. Crow tastes good at 20 fps.
