It shall be interesting to see what the sensors will be like in the coming future. Many seems to like the pixel count reduced to increase S/N ratio, much like Nikon's philosophy. However, ideal pixel size is not really easy to state. Large pixels are indeed less noisy on high ISO, but you cannot trust as much on averaging as you can with higher resolution either. I personally believe that high resolution is a valuable feature, ideally I'd like optics and airy disc be the limiting factor on resolution, not image sensor -- assuming there's not too much compromising with noise and dynamic range. With postprocessing algorithms like lens correction, perspective correction, sharpening etc it's great to have a capture at or beyond optics limits so postprocessing is possible without reducing actual resolution.
I'd like to see new techniques with having multiple simultaneous readouts. If electronic shutters could be made better one could get several shutter times at once, great expanding dynamic range, like bracketing but in one shot. With multiple amplifiers one could read out at low ISO and high ISO simultaneously, and mix them to get lower shadow noise in low ISO images (where read noise tends to be higher than corresponding high ISO readout darkened to the same light level as the low ISO readout). With these techniques combined the RAW files would get extremely large though. DSLRs are quite large though, so I think the size should be used to pack in high performance electronics, large memory buffers etc.
Oversized ram buffer, and option to write to two CF cards simultaneously would be great, to maintain full RAW speed for many seconds. Design the camera so that you are not tempted to use JPEG to get more performance - RAW should be fast enough to be possible to use in all situations. Actually, I think it would be cool with a RAW-only camera too, or at least be able to turn off all JPEG-related features and settings to clean up the user interface.
And yes, radio flash controller should be standard by now. IR/flash triggering feels really really low tech.
It also like to see some new ideas on how to make photo inspection better, something more/smarter than histograms. I'm not sure what, but it feels a bit limited currently, at least for I as an amateur, still it happens that mistakes are not discovered until I look at the photos on a computer screen.
Oh, better remote triggering too. It should be standard to be able to modify ISO, aperture, shutter speed from the remote, in these days of HDR...
