I agree that philipbloom.net is a very good source of informed opinion on video cameras but I would also take his advice and never just take his word for it - actually go down to your local camea shop and test it out for yourself.
This is what he said about the GH3-
"I can’t review the camera as such for now..that will have to wait until a release camera or close to release camera is available but going from what I have seen and used so far it’s a massive step up from the GH2 in build quality, feel, image, low light. All important stuff." Testing out the GH3 is not a reality for almost all of us. In fact testing it at all before final firmware is complicated. Michael wrote a caveat in his prelim. field review.
For those who have had an opportunity albeit limited time with the GH3 - no one has shot anything purposefully in order to test aliasing or moire.
This isn't to say there aren't examples of this. Here's one-

I agree the net is not "buzzing" with interest about the GH3 moire and aliasing - (I got carried away a bit.)
But for those who have interest in these things - there is a concern that Panasonic may have missed the mark in this regard.
Personal View is the site of the GH2 hackers.
http://www.personal-view.com/talks/discussion/4733/official-panasonic-gh3-topic-series-2http://vimeo.com/groups/gh3usersWhy is aliasing and moire a problem at all? The GH2 and 5DMK3 are the only DSLR type cameras that do not display easily noticable aliasing and moire
in video mode. BBC cameraman Johnnie Behiri found that the Sony A99 has a distracting level of aliasing and moire.
Many wish to have a camera with the GH3's specs that is clean from distracting levels of artifacting. I have used the GH2 with success for broadcast work standard definition assignments. The GH2 and GH3 shoot 50i and 25p. which is a requirement for PAL transmission.
If the GH3's final release version is free of annoying artifacting, then at least we have another choice beyond the GH2 and 5DMK3.
