Don't get too excited by scan backs unless you really enjoy shooting at 3 ASA, well they need a lot of light anyway.
I think that this camera has a market size of 3.
Did you read the specs that the lowest speed is 500 ASA all the way to 10,000?
Did you follow the link to see the sample photo is an action shot?
I know more than three people ready to buy, all in China (you won't believe how
rich the riches are there -- one of my friends has 9 Alpas and 3 Glides and they
grabbed almost all the Hasselblad Special Editions), so I'll bet with you on the
market size. Compared to the P45 (39MP) backs at roughly the same price,
this sounds a real bargain and even I am very attempted if everything goes well.
