Recently, we’ve seen engineering advances in sensor design. For instance, OmniVision’s backside-illuminated (BSI) sensor, which started appearing in many compacts last year, moves the support structure to the rear of the sensor for better low-light results. More powerful processing and software play a big role. You can see the effects in compacts, with their growing lists of catchy features from in-camera HDR to super-fast burst speeds at lower resolution. In DSLRs, witness faster full-res bursts (up to 85 JPEGs or 26 RAW at 10 frames per sec in the Canon EOS-1D Mark IV).
