The Fujifilm X100V is expected to be officially announced in early 2020. According to a dpreview user, he talked with a Fujifilm manager, and said that there could be three versions of Fujifilm X100V in testing, some has a tiltable LCD screen, and also weather sealing may coming to X100V.
From dpreview user:
I also got a little bit of gossip from the Fujifilm rep on the x100 refresh: He said that he has seen three mock ups of potential designs, two of which have flip screens (with one modelled on the Xpro3’s). He also said that there have been serious discussions about weather sealing – whatever that means.
