See the existing review of the Sony NEX-7.
Results with the new Zeiss Touit 12mm f/2.8 and Zeiss Touit 32m f/1.8 E-mount lenses will be shot using the Sony NEX-7 and become part of Guide to Mirrorless. I expect the camera and lenses by late this week.
One has to wonder if a Sony NEX-7N (Sony NEX-9?) might incorporate an even better sensor having the same per-pixel quality and pixel density as the Sony RX100; just to speculate: that would be 60 megapixels, but 48 would be just fine with me. Offering raw output at native resolution, or at 3/4 or half the pixel count for elimination of digital artifacts—any form of native oversampling would be hot, and though I deem it unlikely, it is what *I* would do to shake up the market.
Sony did some things really well: built-in EVF, centered tripod socket so a camera plate does not block the battery/card door. In the context of its 2011 release date, it stands out as better done than most current compacts, and 24-megapixels to boot.
Zeiss Touit 12mm f/2.8 Distagon
Equivalent to an ~18mm lens on a full frame camera, this is an ultra-wide angle design. My expectation is for it to outperform most full-frame designs by dint of being newly designed and optimized for the APS-C format and no need to design around an DSLR mirror box.
Zeiss Touit 32mm f/1.8 Planar
Equivalent to a ~49mm lens on a full frame camera, this is a moderately fast normal lens. The f/1.8 aperture and new design give some hope for a very high performance design, with my wish being for a flat field and no focus shift.
