More megapixels, better photos: Fact or fiction?

Yes and no

In general, for a given level of sensor technology (not comparing old tech to new tech) and a given format size (not comparing small sensors to big sensors), a sensor with more pixels will have more noise in low light and less dynamic range. However, these deficiencies are not as apparent in equal output size prints as they seem based upon examination at the pixel level. Furthermore, a big difference in sensor size is typically associated with a relatively modest difference in dynamic range.

On the other hand, given an adequate lens and sufficient light, the sensor with more pixels generally delivers greater detail in large prints. For small prints, there is no advantage to having lots of pixels, whereas the disadvantages mentioned above may still be evident.

More MP is a tradeoff regardless of format. The same tradeoffs seen with the Fuji F30 and G7 can be seen with the Nikon D3 and Canon 1Ds Mk III.
