SonyAlphaRumors is shocked that as of yesterday, the NEX-7 had more pre-orders on Amazon than the A77 does. [Best Sellers in Digital SLR Cameras]
Today the Sony NEX-7 Body Only [$1,199.99] and the Sony NEX-7 with 18-55mm Lens[$1,349.99] rank 6 and 10, while the A77 With 16-50mm F2.8 lens[$1,99.99] is at #15. Should we really be surprised, given the price difference?
What really surprises me is that the Sony NEX-5N With 18-55mm Lens only makes an appearance at #16 [$699.99]. I thought it would be much higher than the NEX-7, but maybe it has something to do with the fact that the NEX-5N is an upgrade of an existing camera, while the NEX-7 is "totally new" (so existing owners of the NEX-5 may be buying the NEX-7...)
The NEX-VG20 is not yet available for pre-order (it's not supposed to ship until November) so doesn't appear in any lists yet!
Which is best for low light? Sony NEX 5N or NEX 7 and A77? | Andrew Reid | EOSHD
Andrew finds some tests at Imaging-Resource, and discovers that the NEW-5N appears to have lower noise at the highest ISO than the A77 does.
This is not necessarily surprising, because if the chip technology is the same, then you would expect that the more pixels in the sensor, then the smaller the size of the individual sensor photosites, and the smaller the size of the photosite, then the higher the noise.
But, as others have pointed out, the A77 is still a pre-production camera, so it's possible that the final camera will perform better.

According to DPReview, the LA-EA2 Alpha to E-mount adapter does have it's own tripod socket, which could be really useful when hanging large lenses off a small NEX camera body.
