one of the most distinctive features of MFDBs is the higher dynamic range, which is mainly due to the different approach of reading the data
Does anyone know of a real side-by-side test which demonstrates this? Link? (I am not talking about anecdotal commentary, but an actual test with both cameras in the same room at the same time.) Just curious as to how much difference there is.

No, I haven't seen such testing, but it would be easy enough to do. It needn't be done side-by-side, current DSLR's have been analyzed already. Anyone with a MFDB they want tested should provide the following:
1. A pair of identical images of a colorchecker chart (GM is fine, others are probably OK too as long as the squares are big enough), slightly OOF and filling a large part of the frame; lens two stops down from wide open (to minimize vignetting but not to introduce dust bunnies); shot at the camera's base ISO (usually 100); metered properly. The images should be shot in succession, waiting for the buffer to clear before taking the second one. Tripod of course, fixed light source uniformly illuminating the target.
2. Same as (1), but three stops overexposed relative to the metering for (1).
3. Same as (1) but three stops underexposed relative to the metering for (1).
I'm rather busy at the moment but would try to make some time for the analysis if RAW files were hosted for download somewhere.
