Is this Samsung's first medium format digital camera?

Look closely at that photo above. Those, friends, are digital cameras from Samsung. That's right, even that boxy one that looks quite a bit like an old-school medium format film shooter. This photo was quietly inserted into a blog post from Sammy about lens design, without so much as a caption to clarify what our curious eyes were seeing. Might this be a future model meant to compete in the highest-ends of the digital camera market? Or is it something cooked up in the lab and abandoned for a more practical and mainstream design? There was a rumor kicking around last summer that Samsung was working on a medium format CMOS sensor and this could be a test rig for just such a slice of silicon. Whatever it is, we're intrigued and we'll be keeping an ear out for more info on what the Korean company has brewing.
