I'm quite likely to buy the a6000. I'm just waiting to get a look through that new viewfinder (there are mixed advanced reviews of it), and of course waiting to see if there are any unforeseen glitches.
I like the NEX-7 quite a bit. I would use it even more if it had just slightly cleaner medium-ISO image quality. Its files are kind of gritty, but excellent for smaller print sizes. At ISO 100, I find the files to be quite good for fairly large prints. But above ISO 200, quality starts going downhill fast as print size rises. I'm looking forward to seeing what Sony's latest sensor can do about that.
The range and quality of lenses available for apsc e-mount are now more than acceptable: zeiss, sigma, some of the sony lenses, samyang autofocus on the way. I like the trade-offs apsc gives me for depth of field and/or hand-holdable shutter speed.
For hand-held use, I think the a6000 could be a winner. Very quick and responsive, with an EFC low-vibration shutter, small and lightweight. From some of the early files I've seen, it looks like the a6000 might be very close to the A7 in image quality at low and medium ISOs. For $650, I might get a couple.
