The Pop Photo articles I've read on these "full frame" DSLRs rarely
if ever talk about the image quality advantage of moving the pixels
further apart in the sensor. Mostly, they like full frame DSLRs
because 35mm camera wide angle lenses retain their full wide angle
potential when used in these DSLRs.
Some of these cameras support a technique known as HDR or high
dynamic range imaging.

Essentially when you take the picture there are three exposures,
which are then combined to extend the dynamic range of the image.
I've seen this in Photoshop before; yesterday Apple announced that it
is included in iOS 4.01 and the cameras in the iPhone 4 and new iPod
Touch now offer this as a shooting option.
