Not from what I've read- the 30-minute limit just has to do with where you buy the camera. If you buy an EU model it will have the 30-min limit, all others will not. All the cams from anywhere can switch between NTSC to PAL. So EU people who need unlimited record will have to import a cam from the US or somewhere else.

Yea... much cheaper than the Atomos, albeit without a built-in monitor, but a good option for those who are happy to use the camera's screen, or already have a monitor they're happy with. I just wish the Hyperdeck could do >30fps for 10-bit 4:2:2. Perhaps a new (but still affordable) model will be unveiled at NAB, or if we're lucky, a firmware update.

There's a SpeedBooster for Minolta lenses, too, you know.

Expressing the increase in brightness via F-stops ("turns your lens into a f0.74!!!!") is what's so confusing for people, because people tend to think of DOF in terms of F-stops. I think people have a better grasp of differences in DOF if they are expressed via sensor sizes: Exactly. For FOV and DOF, think of the Speedbooster as attaching to and modifying the camera, not the lenses. Meaning, think of your camera as now having a larger sensor (exactly how much larger depending on which SB model you're mounting to it). For exposure (brightness of image), think of the Speedbooster as giving your camera a "free" improvement in ISO (meaning a brighter image but with no additional noise/grain). So you think of any given ISO on your camera as one stop (or 1&1/3 or 1&2/3 stops, for these new SB's) brighter, but with the same noise. So, if I have a Pocket, and get the new Pocket-specific Speedbooster, I will think of it as turning my sensor into a 1.74x crop/slightly-smaller-than-Canon-APSC/slightly-larger-than-GH2 size, and making the ISO performance 1&2/3 stops better.

Amazing! Hopefully they eventually do a Minolta MC/MD version.

Consumers probably won't even be considering the GH4, as it will be part of the Panasonic pro/prosumer line, not the consumer line. Most of them won't even know of its existence because it won't be at the normal consumer outlets- Best Buy, etc. But the true successor to the GH3, the GH5 or whatever they call it, will be, and it certainly will have 4K, but probably just at 8-bit 4:2:0. And of course at a high consumer price point, say $1400-1500.

I don't see how a GH4 could do 4K 10-bit 4:2:2 at only 200mb/s. ProRes 1080P 4:2:2 is 220mb/s... and intraframe of course, but it's still only a quarter of 4K's resolution. It seems like 4K would have to have a ridiculously long GOP to fit into 200mb/s at 10bit/4:2:2, which would make motion look weird. Personally I would greatly prefer to have an excellent all-i 1080p with lots of detail and color info and frame rates, than an uber-compressed 4K. Hopefully the cam will at least give us both.

I too am awaiting the GH3 user's guide! New camera announcements and theories are great and all, I follow them as much as anyone else, but I want help with using a camera that's available right now. Please finish up that GH3 guide!
