EDIT: I'm not surpised that Sony was able to make such an improvement. In general, mobile phone cameras and digicams have had much higher performance per area than DSLR. The R&D budget, revenues, and technology level are all much higher in that space due to the very high volume. Sensor designers such as Eric Fossum (inventor of CMOS sensors) have commented that the design of sensors like the 5D is very simple compared to mobile phone cameras and he's looking forward to seeing Canon and other DSLR manufacturers push the envelop more in the future. I am too.
