According to a report on Fuji Rumors, several sources have told them that Fujifilm has plans to completely drop their line of diminutive line of Fujifilm X-E series cameras. The Fujifilm X-E3 was released in September 2017, and fans of the line have been awaiting the X-E4 to show up for a while. But now it appears it may never come.
The X-E series is a popular line, with the exception of the Fujifilm X-E2s. As one of the smaller bodies in the Fujifilm lineup, the X-E was a great walkabout camera but also had the chops for some more serious stuff, too.
