Just a silhouette thus far though it is enough for everyone to form suppositions on the new Fujifilm camera system. Likely to be the flagship model for the popular X-Series, the DSLR-style model will include a mirror-less system like those found on the Fujifilm X-Pro1. But with its competitors pushing the technical boundaries, like the full-frame image sensors found on the Sony Alpha 7 and 7R, there is a probable likelihood that Fujifilm will do the same. Additionally, the eagle-eyed writers at DPReview pointed out several clues...
Shutter speed dial with X-Pro1-like locking button
Exposure compensation dial covering +/-3 EV
ISO dial (also lockable), including 'A' position for quick access to Auto
Control levers below shutter speed and ISO dials (function unknown, but drive mode would make sense)
Movie record button
'Fn' button which activates built-in Wi-Fi
Power switch surrounding shutter button
Large viewfinder hump, perhaps implying extra-large EVF
PC sync socket on front
Electronic front dial below shutter button
All is set to be unveil next Tuesday, January 28th.
