There are some pictures that are almost certainly the R1 floating around. Overall, I like the look of it, the general layout, etc. As for the rumor'd specs, I am constantly reminded that 24 MP is enough by the 24x16 prints I have on my walls from the 7D and 5DIII. 16 bit RAW is potentially interesting. As would be the Quadpixel AF, granted, it is very rarely I run into issues with my R5, but hey, it is likely better. Overall, it seems like what the "1" series has always been, work horse flagship. The best and most dependable. A dependable tool that will help you get the shot.
