I think I speak for all of us when I say,
Is Oosting looking to take Hasselblad into the purse space? The man-bag space? B&H lists the bag, no picture, for $350.
A dedicated bag designed to hold the system and (one imagines) not much else, speaks to the complete unseriousness of this thing. It tells us that this thing is a status symbol, not a tool. While it is, obviously, a capable instrument, it's not intended to be purchased by people who will use it as such. Just as the Ferrari is a capable track car, and the Bottega Veneta purse can indeed hold your lipstick, this is a capable camera.
In my former industry, we distinguished between the "thing" and the "complete product", and in this case the thing is a superb camera, within certain parameters. The complete product is a bag, a camera, some lenses, and a ton of status. Mainly, it's status. At least, that is how it is positioned.
