Each of these manufacturers have come up with sensor/software that produces unique 'looks' to their camera outputs. All of them are gorgeous in their own ways. The one plus-side feature that the X-Pro1 and X-E1 cameras offer is the lack of an anti-aliasing filter. This is not a minor issue in my mind. Being able to produce large prints that are still very sharp, with no image softening caused by an anti-aliasing filter is very useful.
The GXR, E-M5, and M9 all also have no-AA filter, Jamie.
