Also - the NEXs are limited to 29 minutes of continuous video. This is a problem for sermons, school plays, speeches, graduations etc. These events are rare, but when they come up, people don't want gaps caused by camera restarts.
If Sony gave us an NEX or Alpha cam with unlimited clip length and moire close to the Panasonics, they would have a lot more success in video world.
I am not a Sony hater - their NEX-VG20 camcorder solves the clip length problem - and does a good job with moire. But the NEX-7 is a flawed video camera, in my opinion.

Well I picked one up after reading many of the reviews and so far I'm very very impressed.
In my testing thus far, I've seen one case of a bit of moire, but nothing to get too nuts about. What I am seeing though relative to my GH2 (as can also be seen in your comparison link), is considerably more detail and better color. I'm using the highest bitrate 60p setting and it's really nice. If you notice in the comparison link you posted, I still see a bit of moire in the GH2, but more importantly I'm wondering if the NEX7 showed more moire in the brickwork simply because there was far more detail. In some areas the GH2 just looks mushy and therefore not enough detail to create the moire in the first place. I think that may at least partly explain it.
I just went back to look at that side by side again and there are some parts of the picture where there are more artifacts in the GH2 than the NEX7. Take a look at the picket fence (or whatever it is) near the boats. You'll see artifacting on the GH2, but the NEX7 is clean. I guess it depends on what your subject is.
Having full access to all settings in the video mode is new for Sony in the NEX line and much welcome in the NEX7. I had an original NEX5 (not the current model) and really hated the 24p and very bad moire & aliasing. In the NEX7 it seems to be far better controlled.
I can also tell you the OLED VF is out of this world. It's really a new experience in viewfinders.
I'll be testing the NEX7 against my Canon XA10 for fun. The Canon produces some of the best video I've seen in any consumer/prosumer camera, so that should be interesting.
BTW, I think it was DP Review (not 100%) that said they found no time limit in the length of video. They apparently went well beyond 29 minutes with no issues. They may have said they filled up the card, but I can't recall exactly. Either way that's not an issue for me since I don't shoot long events like that.
I'll let you know any further observations as time goes on.
