I want one.
The only thing stopping me is the matter of money. (Send checks, money orders, cash, coins, stamps to ....)
Aperture64's comment about TLR's is true for me, too. A pain in the a$$. I might have to sell my Rolleicord. I love the big negatives, but the process of composing with WLF is too unnatural for me. A big Leica-like vf/rf is probably a solution. I wonder if Mamiya has ever considered shoe-horning their digital sensor into a 6 or 7 body?
