It's funny you said the d800 is changing things. It's not.
That's what they said about 35mm film
That's what they said about the 1Ds
That's what they said about the 5D2
That's what your saying now with the d800
Quite frankly, MF is here to stay and will always be ahead of 35mm. The more pixels you add to 35mm, the harder and harder it gets to make lenses that will suffice, while MF will stay at a lower magnification thus making it simpler to keep more pixels sharp. I love how you bring out the ludicrous DR debate when it's not even relevant. LoL, current MF shooters will always shoot MF because of its mechanical advantages over 35mm + the superior IQ of MF.
You said the d800 is already optimized at 36MP but the IQ180 is at 80mp! LoL, no comparison.
Edit: oh, yes I would still choose the Hasselblad over the d800 for syncing at 1/800th and the ability to use schnider Lenses and tilt-swing bellows.
