Ugh, with a RAW file size of what? 120MB?

So?  Storage is cheap, and my computers are fast.  ;)

I upgraded yesterday from Pentium 4 3GHz-PC to a Core i7 CPU-Machine: What a progress ... its computing power is great but data transfer might become a bottleneck during backup etc. ...

Agreed. Although that extra CPU/RAM boost will definitely aid in processing those potentially hefty image files, if you throw in a couple SSDs in RAID configuration, your startup times and data transfers would be greatly enhanced. Plus, they are relatively cheap these days ;)

My preference is to set up two SSDs in RAID 0 and use that for my applications and data that I need fast access to, then I'll use a couple terabyte 7200 rpm drives in RAID 1 for the rest of my storage needs. Never had a problem in over 10 years.

Very interesting. I just hope that one of the big MP cameras we keep hearing about comes with 16-bit DR. I can care less about any camera with more than 40MP and doesn't have 16-bit DR...

Yeah, but it will take 10 hours to backup 10 photos to another HD.  ;)
And maybe 10 months to back up a a trip. ;)

Maybe if you're using USB2. At 10 Gbps with Thunderbolt, it'll be plenty fast.

Even with USB 3.0 (or TB) backing up a few 3-4TB drives is still a MAJOR drag.
This is the biggest downside IMO.

That said bring on the MP, one way or another people will deal.

Picture this, in the 70D, Canon now has a reliable two-pixel bin for which the alternate channels can be used for AF, but combined for imagery. Now, let's take that same general tech up to full frame, giving us approximately 80 semi-pixels. Now refine the tech ever so slightly and:
1. Allow the bins to be broken so each semi-pixel is individually addressable for maximum spatial detail of 80m px.
2. Allow octal bins (dual-semipixel, binned Bayer quads) for maximum color fidelity and DR at around 10 mpx.

Truth is this is version 2 of the high MP camera in early testing.  How do I know - because it must be true; a little bird told me so

What confuses me most about this news is why it is in CR's Canon General section and not in the EOS Body Rumo(u)r section.  :o

Apart from that, it's great news.
1D X + backup + different L lenses etc.

Finally Canon has listened to its millions of day-to-day users and gave them what they have been asking for. At last, a camera that adequately meets the desperate needs of cat-lovers for a high-resolution RAW file. Bring it on. Now smile kitty kitty.

If you can care less, then why don't you ? ;)

As far as 16-bits....now that is something I could not care less about. Because 16 bits will not give you more DR. Just bigger files with the extra bits quantizing noise.

14 bits will do just fine.

Not particularly believable.

For this product to work, it needs several other pieces of the puzzle:

1. Higher resolution on the same size CCD/CMOS means a process shrink of around 40% to add that many pixels. It isn't directly comparable to say a CPU, which can do other things like make large chips, rearrange the internal parts. Given that a cameras chip is made of few components AND have to keep to a similar size/aspect ratio, there is less flexibility to use these methods.

2 . Better Digic processors to move the data off the chip onto memory cards. You wouldn't go for a camera that has higher resolution and lower frame rates would you? I wouldn't.

3. Given the influx of new 4k video cameras and monitors capable of displaying the images, people would probably want this also, and if you have the sensors and DSP capable of the above, you would want this.

4. Storage space for the resulting photographs/video and CPU capable of editing/storing it would be fairly large but not out of this world expensive. Most people would need to upgrade.

1 and2 are possible, 3 would make this camera compete with their "C" series video cameras and 4 would be a new expense for the camera buyer to pay for..

2015-16 maybe. Not 2014 unless its some "leak" to keep people from upgrading to a Nikon

actually......
A pixel produces an analog signal that is relative to the amount of light it has been exposed to. That analog signal is sampled by a D/A converter and becomes a digital number. The number of bits of resolution of the D/A converter is the upper limit of the DR of the camera. If you have a 12 bit D/A, the best dynamic range possible under ideal conditions is 12 stops. If you want 16 stops, you need 16 bit D/A and that means 16 bit RAW files.

and for those wondering how fast and accurate you can go.... I have an 80Ghz spectrum analyzer at work that samples at 24 bits.... that's like sampling every pixel on a 75Mpixel sensor 1000 times per second at 24 stops of DR! Cameras are snails in comparison...
The best camera is the one in your hands

I'm not entirely sure of the technical aspects, but wouldn't this many pixels result in severely reduced high ISO capabilities? Would Canon have to innovate somehow to keep the ISO capabilities on par with other, lower megapixel DSLRs?

He said 16bit DR not 16bits  ;) so I'm with him, bring on the DR.
