It could be an exciting week, depending.
Sony is expected to announce a full-frame high-resolution NEX (according to rumor sites and I deem this highly likely also). There is a decent chance that the sensor design could be friendly to Leica M lenses. Of perhaps equal interest to some users might be a NEX-7R, (it’s about time), perhaps with the latest Sony high-res EVF and other improvements.
Nikon is having some kind of announcement and there is an outside chance that a 54/56 Nikon D4x could be in the offing, though even if it were so, I’d not expect to see one prior to 2014.
