Two Duels: Nikon D800s vs Medium Format cameras

The Nikon D800s (the D800 and D800e as a group) have thrown down the glovelet (glove + gauntlet) and have challenged the world of medium format cameras. Two independent duels have been posted the last couple of days:

+ Nikon D800 vs Phase One IQ160 digital back at Camera Labs
+ Nikon D800e vs Hasselblad H4D-40 at Photigy (part #1, which suggests more is coming up later on)
