If Sony play their cards right, they could effectively take over the entire landscape photography market - DSLR as well as medium format - with a single release, and cement their position in that market for years to come.
Sony has patented the Exmor sensor, giving its CMOS sensors dynamic range previously held only by CCD sensors. At the same time, these CMOS sensors retain the tradition CMOS advantages of high ISO performance, live view and lack of blooming. The DSLR sensors based on this technology, as used by Nikon, are the best in their class.
At the same time, Sony has an association with Zeiss. Zeiss makes superb optics, both for DSLRs and for medium-format systems.
Finally, Sony is a world leader in electronics, but isn't so good at the mechanical side of cameras. A mirrorless camera is an entirely electronic device, and, for landscapers, has the advantage of being smaller.
What Sony could do is release a mirrorless panoramic camera with a 24x72mm sensor (same aspect ratio as 617 film, or two 24x36mm sensors side-by-side) in the 70-100MP range. At the same time, release a range of Zeiss lenses designed for the system - 24mm, 30mm, 50mm, 100mm and 200mm would be a good set. Being mirrorless, the lenses need not be particularly large or heavy. It'd have the IQ of the iQ180, or 617-format film, while being more portable, more weather-sealed, with proper live view and autofocus.
It would effectively kill off Linhof, Horseman, Alpa and other medium-format field cameras in a stroke, put a serious dent in Nikon, Canon and Leica's armour, and cement Sony as a world leader in digital cameras. All by making what is essentially a scaled-up NEX-7.
