Dqqq: I was about to buy a Nex-7 body yesterday but I'm going to pre-order the Nex-6 with lens now.
-EVF-hybrid AF-touch screen-Flash (probably not very good but at least its built-in)-Standard hot shoe-secondary control wheel (which a firmware update will probably allow to control more settings)-a more compact lens which covers my 2 current e-lenses - almost (16mm and kit)
Wish it had a plug for an external mic, but at least i have a place to mount it now! (coming from a 5n)
The three new lenses could shake things up and breath some new life all of the nex's
Just to add to the discussion Nex-6 v.s. Nex-7 ... I had the opposite feeling, I bought a slightly used Nex-7 body for 875$, a week before the announce of the Nex-6.
Of course I asked myself if I would sell it and bought the Nex-6 instead (same price). I have been searching for a small yet professional camera for a long time. Devil is in the details, but the Nex-7 is still the one that offer DSLR control equivalency and that's why I choose to keep my Nex-7.
Again in the detail, the metal edges and the clean and silk feel and look make the Nex-7 a pro instead of a semi-pro instrument. When I saw the control of the Nex-6, I thought of the Canon G12 (can get this out of my mind, it's obsessive)
Of course many other criteria (which you listed) could have played in the balance,
