And what about perhaps the best example: Act of Valor. It is shot for about 75-80% (amount varies, for what it's worth anyway) on DSLRs (5D Mark II, 7D, .. yes no one stop shop on the DSLRs).
I doubt it used that much DSLR for the whole feature, but the basic remains the same. If it's good enough, then just don't bother with new & more expensive equipment. You don't replace a good hammer because the new model became available at the local hardware. Once you've learned how to work with it you feel more confident as you know how it'll behave, sort of.
I did not work with Hurlbut on the movie and have not seen it either yet (I think it hits blu-ray and dvd sooner than the big screens in Europe), so you will have to argue with Hurlbit. At 5m20s he mentions the 80%.
