In a recent interview with Focus-numerique, the head of product planning at Samyang Jeong Min Shin said that autofocus lenses will be coming also for Nikon and Canon mounts (already reported here on PR) and that the Fuji X and Micro Four Thirds markets "are not very important" and will not get any AF support:
We started the implementation of an autofocus optical FE frame and we are adapting to of other mounts, like Canon and Nikon. We also believe in Fujifilm and Micro 4/3, but these markets are not very important
Samyang already announced AF 14/2.8 and AF 50mm f/1.4 autofocus lenses for Sony FE mount.
