The main advantage that stands out is better low light performance, able to capture low light action that PS cameras often miss (an advantage due to large sensors). There is also the advantage of better bokeh with shallow depth of field (more difficult to get with a small pin-hole lens of PS cameras) and true 1:1 macros. Another advantage is better flash system, able to control multiple flash (but few non-pros really use this). RAW file is not a unique advantage, some prosumer models have RAW file capability.
No doubt, PS cameras are loaded with features, but D-SLR still rules in low light action photography.
