Interesting. I've got a D200, and it made think about whether I'd want to upgrade to a 12 MP version if true. I'm assuming the primary reason for a sensor upgrade would be to eliminate the banding-tainted 10 MP sensor and maybe tweak Canon a little in the process. For new buyers, having a sensor without banding would be a plus. However, having used the D200 since January, and having it adjusted once at Nikon, banding has never been a problem. Also, I'd be a little concerned about the noise level of the new sensor, and the need more computer power to process the files. So, let the speculation begin. I can live with the original version. :> )
