This is no joke: Today Nikon announced the J4 camera and you know what? They decided to not release the camera in USA! So it will be available in Europe and Asia only. Probably the reason behind that is that the US market is still "not mirrorless friendly". Canon took a similar decision with their newest mirrorless camera.
Anyway, the new J4 has the same V3 18 MP sensor and an amazing Af system with 171 contrast and 105 pahse detect points.
