A nice bit of kit, but if ever the term "who's it aimed at" was to be used this is the kit I would aim it at. I can't think of an area of photography you would get a good return on your investment, I can think of a few occasions I could of put it to good use, not nearly enough to get the money back let alone turn a profit. Landscapers would need to sell a lot of prints, picture libraries couldn't care less about having a file that size, no doubt you would have to down size it. Even then they would sell the image for $20. Maybe I'm missing something, I just can't see a big enough market to justify owning one for sound commercial reasons. I would like one, honestly though I could make a more convincing case for spending the extra on a P45+ or even a P65+ .
