This looks cool. But I'd want to get one in my hands before buying it. One of the advantages of the larger camera bodies is that they fit well in your hands, which makes it easier to hold when larger lenses are attached. I have a hard time envisioning this being a comfortable camera for any but the smallest of lenses.
This camera looks incredible. Carved from a block of aluminum with super clean controls and a great minimalist design. The iPhone of cameras. B&H Camera shows it for $1999.
