Sony's got a new sensor. 12MP and capable of 10.5 fps. http://www.sony.net/SonyInfo/News/Press/200708/07-072E/index.html The only questions I have are about the noise on a beast that small. I am sitting on the fence for my own system. Don't know whether I want to go Canon Mark III or the hopefully soon to be announced Nikon D3h and D3x a few months afterwards. The history behind Sony and Nikon sharing sensors is that they usually build their bodies for them until they are finished with testing, then drop them into whichever camera they will use. The D2x sensor was supposed to be used in the D1x but it wasn't anywhere near finished. That would have given Nikon the upper hand on the Canon 1Ds Mark I almost six years ago, but such is history. I shot Nikon at my job, and own a D200. I am looking for real pro gear hence the decision between the Mark III and D3. If Nikon doesn't goof like they did with the D1x D2h and F5 I will gladly pick up a D3 and buy a bunch of my jobs used lenses and bodies off of them. If I go Canon, then I will have to grab a Mark III and do a couple of jobs to afford the L series glass and some Metz flashes. I really hate this back and forth with Nikon, how I miss film.
