By this logic all hacks/patches must render near identical detail...
...and let's not forget, there's no details given regarding camera settings, lenses, the method used in editing, or anything at all to give a sense whether the uploader knew at all what they were doing.
Then there's the issue of even if this is the same chip as the GH2 it doesn't mean they used everything else. It doesn't mean the baseline, stock compression is even as good as the under-achieving stock settings on the GH2 or whether it can be opened up yet.
Basically, judging this camera based on these clips isn't intelligent. Period. It might suck. It might offer even more hackable potential than the GH2. Nothing in these YT clips are a valid indicator of anything.
