Fujifilm has a press conference scheduled for January 7, 2013 (next Monday) just prior to CES 2013. Photo Rumors is reporting that the Fuji X100s and X20 will be announced that day and will both be similar to the X100 and X10, respectively.
The Fuji X100s should contain the same leaf shutter as found in the X100, which is great news. The X100s should also offer focus peaking as an additional feature to aid in manual focusing.
I’ll have more on this from CES 2013 (hopefully live).
