"This mpix discussion is so ridiculous. What the hell do they expect, 18mpix is state of the art, why should they suddenly reduce it? And even more, why for the xxD which is a consumer/prosumer cam..
How can ppl. even think about that?"
This is a typical technie mentality. more is better, newest is also better. 18MP sensor may be state of art (in the Fab processing). That does not mean is best for the picture quality as mentioned in various web site and test sites.
