What strikes me odd is if Canon makes this camera, it would mean their highest MP camera would be an APS-C format body, not full frame. That just doesn't sound logical, why would they do that? This camera would have a pixel density equal to a 61mp full frame camera, that is far beyond the resolving power of most lenses. I doubt this camera would really come anywhere close to the IQ of the 5DmkIII, that is just wishful thinking, at any ISO.
From past experiences, the a lot of people who buy a 7D aren't "pro's" etc etc. The most of them see that it's a professional
looking camera so they target it. Then those who haven't been in the photography world for long would brag to their other friends (who don't know so much about photography as well) that their camera is "24.1 MP" which is what most consumers who are looking for a camera look for the higher megapixel. And those who do buy are mainly Asians (not sounding racist. I'm half-Asian) and Canon was rated as Asia's number 1 brand (well the several billboards I saw in the Philippines say so at least). With saying that it easily attracts newcomers to buy such a camera (especially the ones willing to spend $2000 and flash it around).
I honestly hope that the 24.1mp isn't true. I loved the 18mp all I really wish for is improved ISO performance, update the AF system, and I hope they keep the pop-up flash!
