Andre, I'm not familiar with the binning technique you are writing about. I have a vague idea what it does and that's it. Regardless, I'd like to see them continue to up the ante by being able to flush the full MP's at higher FPS rates, then maybe give the option of even higher FPS with binning or sRAW type tricks.
sRAW and Pixel Binning are the same thing!
I hear you on the higher FPS. I was basing my #s on what the D4 can do today. No doubt as the technology improves, the higher FPS bodies will pound out the frames as lower MP bodies.
At some point, mechanical performance and AF aquisition time become the limiting factors. I'm not sure which become the limiting factor first, but I suspect that the AF aquisition time will be the limiter. There are plenty of mechanical devices that run at greater than 10Hz (i.e. 10 FPS) but it will require greater precision & more expensive materials to do that in a fragile camera body with a glass mirror ... all of which drives up cost.
All that aside, I could see Nikon coming out with a D4X that looks like this:
FX RAW @ 54MP, 3 FPS, 2 second buffer
FX sRAW @ 13.5MP, 10 FPS, 4+ second or longer buffer since the smaller files would clear faster
DX RAW crop @ 24MP, 6 FPS, ~3 second buffer
DX sRAW crop @ 6MP, 12 FPS, near continuos shooting till the card fills.
That would be a very versitile camera. No doubt the DX crop will be there... but will the sRAW be there? Nikon will do it eventually, but in a D4X ?
Now some day in the future, you will see that 54MP at 8 FPS and a 5 second buffer ... just not now. ... but for your sake I hope I'm wrong.
