In addition to the compact cameras, on January 7th, 2013 Fujifilm will announce also the new X100s and X20. Both cameras will have bodies similar to the X100 and X10. The Fuji X20 will be available also in silver (similar to the X100). The lenses on the new models will remain the same. The big news is that Fuji will add focus peaking to the X100s (not sure about the X20). This will significantly improve the manual focus of the camera. It will be interesting to see if Fuji will release also a firmware update that will add focus peaking to the X100 and X-Pro1. The X-Pro1 replacement will not be announced soon (maybe at the end of 2013).
Update: I received some more details on the new cameras - see this post.
