I view this like over-clocking with todays CPUs and GPUs. You can buy Intel or AMD Black CPUs that will work perfectly under the designed spec, but Intel also gives you the option of over-clocking your CPU to the point where you may increase it`s performance by as much as 200 percent. Yes, you pay more for these Black CPUs, but Intel / AMD does nothing to prevent you from over-clocking their hardware.

Ah, your analogy is completely flawed. AVCHD is not hardware, it is software.

What do you base your confidence that ist the G3 sensor? Bearing in mind the Specs (Rumors) suggest a new EDR sensor.
But the AVCHD spec controls what the GH-2 software enables the hardware to do, much like the software based over-clocking engines that Intel / AMD / nVidia build in to their hardware/software that's found in most of today's computers.
Why the heck can't we have an "overclocking" equivalent in our camera hardware, the same way that the current CPUs and GPUs provide this?
i.e. I can control both the CPU and GPU performance via the software my computer runs on
What? The AVCHD spec controls how video content is written to a particular format on your SD card. That's it.
Nothing like that at all.
You do. It's called "hacking the firmware". It's simply not going to be something that Panasonic will EVER put into their cameras (or any other manufacturer for that reason). That's it, end of discussion.
...If cameras were to mimic the computer world, all it will take is for one manufacturer to decide to change the rules of the game, and offer more than standard AVCHD spec modes, and then the free for all starts amongst other manufacturers. It seems like right now we have a completely artificial barrier put in place by the current consortium of manufacturers.
You don't know that its a completely artificial barrier. There could be hundreds of reason why the AVCHD specification was decided upon in this manner. Those of us who don't mind living on the edge and have taken the opportunity to hack the GH2 understand that our cameras could completely die come, say, December 21, or that something else could go wrong at any time. Same as with overclockers.
I've built 60 custom computers over the past 20 years ( for myself, for friends, and workstations for work ), many of these ran over-clocked continuously. I've never experienced a failure from over-clocking, and I've never heard of anyone I've ever met who has had a computer failure from over-clocking. I am sure it happens, but if built properly the failure rate is very very low.
If Panasonic offered a "Black Edition" of one of their cameras that had user customizable encoding/recording settings, that came with a limited warranty ( you fry it and it's your problem ), I think that there would be many video enthusiasts that would pay a significant premium for this feature, especially if it offered 4:2:2 color-space. Maybe the numbers would be too small to make much of a financial difference, but it would be a big coup for Panasonic in terms of brand promotion.
"GH-3 Black"
...And then they could add mag-wheels with racing stripes and a 427 V8...

Exactly. They won't risk it.
Doesn't matter what the of warranty says, if the camera fries, it will be Panasonic's problem, and that will never happen. You don't see Intel selling 5GHz overclocked CPUs, now do you? Why do you continue bringing up this analogy? It doesn't work on either side.
...Actually they do. They sell "Black Editions" ( AMD does this too ) which are specifically designed to be over-clocked. There are no artificial barriers in these special CPUs, so you can over-clock to any speed that you can run stable at. These CPUs cost a lot more, but the reason they exist is to to be over-clocked.
The same site also mentions that it uses the sensor shift IS for movies as well as stills. I think the previous Olympus cameras have disabled the sensor shift IS for movies and used a digital IS instead. Could be interesting for people using non-stabilized legacy lenses.
The official release announcement should be in the next few hours. Unfortunately is looks like a lame video implmentation. I'm not up on the technical aspects of video, but it looks like just 30 frames per second sensor output. I can't see a video crop mode or peaking mentioned either. There is the claim about the new advanced IBIS being available in video mode. It's a bit of a bummer for me, because the E-M5 is the sort of stills camera I was looking for, but really I still need a GH2 for what I want want with the video. I was just about to get a GH2 and only put it off to see what the E-M5 brought to the table. Unfortunately it looks like I will have to get both to cover what I want. Not the end of the world but a pain. Lucky they aren't too heavy so carrying 2 around won't be so bad. But I think I'll get the GH2 in the mean time and wait to see how much the early adapter prices on the Olympus to drop.

59.94i at 20Mbps. Those rumors that it would trump the GH2 seem to have been exaggerated.

Sometime Nikon (me) shooter or Canon one criticize them about xyz thing or specification, but it is when you look at clueless company like Olympus that you understand why Nikon/Canon brands are dominating the dslr world. Olympus has no video line to protect and yet they are clueless. Some good advance video quality would have helped differentiate their product a bit like the gh2 has a niche right now. Putting 60i interlace in an enthusiast/pro body in today world is just dazzling. They did innovate with the mirror-less camera, but now they have contenders like Sony, Nikon in this market. If they don't find some good differentiating tech etc they will soon go the way of the dodo.
