There are plenty of new mirrorless camera to come soon. The ultracompact Panasonic GM1 will be announced on Thursday (October 17). The new Sony A7 and A7r FF E-mount cameras will be unveiled on Wednesday October 16 and the new Fuji X-E2 on October 18. Here are some more tidbits about the Fuji camera (via Fujirumors):
1) the WiFi on the X-E2 will have more options as the WiFi on the X-M1 (what option would you like to have?).
2) it will have face detection as the X-M1.
3) the Q menu moved to another, better position (where would you like to have it?).
4) video mode will be improved and allow full manual control.
5) no tilt screen / no touch screen.
6) the second generation X-Trans sensor with phase detection AF
7) faster EXR II processor
8) better LCD
Obviously the X-E2 will almost exactly look like the X-E1. I wish Sony would use the Fuji design team for their FF mirrorless camera design :)
