Nikon 1 will have 4k

Actual quote from the article:
"the [J1 and V1’s] sensor is capable of 2K (2048×1080px) and 4K (~4000px horizontal resolution) video and in the future we hope to incorporate [these functions]"
Or, as I read it, the chip could shoot 4K - it has more than 4000 horizontal lines. They'd like to add 4K functionality in the future.
In my opinion, saying that 4K is a feature that Mr. Yamamoto hopes to incorporate in the future and saying that the "Nikon 1 will have 4K" are rather different things.

Isn't he missing the point rather? Any sensor larger than 4K can shoot 4k, given the rest of the infrastructure. My Canon 550D could shoot 4k if it had the processing power to deal with that much data, and if it incorporated a storage medium fast enough. The obstacles to shooting in 4k res are many, but the sensor is not one of them, the problem is dealing with the data. Hell, the Canons have an 18MP Sensor, so given an onboard SSD and a faster processor they could shoot 5k!
On a more positive note, it does signal that they have the ambition to develop DSLR 4k shooting, which means they are taking the DSLR filmmaker market seriously, and others will surely follow.

Actually, they are pretty close to being able to process the data already.
Look at the samples at the bottom of this page:
http://www.dpreview.com/reviews/nikonv1j1/page9.asp#slowmotion
60fps at 3872x2592 is pretty damn impressive!
It's even writing out RAW + JPEG!
Even if it can only do it for 1/2 a second before the buffer runs out...

in any case, keep in mind that this camera has very limited dynamic range, even compared with other small cameras (with bigger sensors): http://www.dxomark.com/index.php/Ca...brand2)/Nikon/(appareil3)/737|0/(brand3)/Sony
Not at 24fps+. There is a reason most DSLRs lineskip and bin, their sensors simply can't run fast enough at full resolution. The sensor is actually the largest stumbling block of shooting high resolution at motion framerates.
either that or the processor cant prcoess fast enough the huge amount of data which could lead to overheating OR could build a processor with insufficient codec capability aka mud

Well, I'm sure they'll increase the bitrate along with going 4k. Then you can scale down to 2k if you want and it will still look nice.
RE: dynamic range... again there should be a slight improvement as you are scaling down. Noise reduction software works better given a high-res signal - and that effectively increases both dynamic range and bit depth somewhat.
Also your bit depth improves a little too, since you are averaging 4 8-bit pixels. As long as there is some noise to prevent macroblocking in the compression, it should help quite a decent chunk.
Also, the mere act of scanning the full sensor without binning or line skipping should improve things too.

I think a global shutter should be the priority.

And there I was, happy with the idea of a tiny, cheap 4K 60fps camera. Guess you can't please everyone!
OK I'll chip in - Genlock or some kind of shutter sync would ROCK. Two little Nikons on a tiny 3D rig would make the smallest, lightest 4K stereo setup imaginable!
