More information is becoming available about this camera (Fuji X100). Here's a hands-on preview of the camera. There's still a lot of speculation. Interesting points: the VF has three modes, an OVF w/digital overlay, a pure EVF, and a playback mode. Also, it looks like manual focusing might be achieved using a method called, peaking--where colored pixels generate around areas as they come in focus (maybe in EVF mode only, though?).
