Optics. The wider the lens mount, the more freedom have the optical
designers. And as digital sensors do need optics that have more
coincident rays than say a film Leica, larger lens mount means
benefits in that.
Personally, I would like a FF sensor just because there currently are no
superfast lenses in APS format. Like Nikon's excellent 1.4/28mm or
Canon's 1.4/24mm lenses, which quite loose their purpose on 1.5/1.6
crop cameras... Once we get f/1 16mm lenses for APS, that could
change.
Good light!
