A thread has popped up on a forum talking about a 46mp pro Canon DSLR being launched in New York City in October for PhotoPlus. It's also mentioned that the camera will cost in the range of $8000-$9000 USD. I have no idea if this is a troll or not, but it will surely appear other places so I might as well post it.
If the EF 11-24 f/4L is indeed real, then it makes sense to announce it with a full frame camera.
If it's true, there will be more to come.
