Aptina announced a new 1″ 14MP sensor (AR1411HS) that can output full 14MP resolution at 80fps and is capable of shooting 1080p at 120 fps and 4k video at 60 fps. The official press release (attached below) describes a “strong interest from several top camera companies that have sampled the image sensor”. Since Nikon uses Aptina sensors in their mirrorless cameras and you can already take short burst of 4k video with the V1, I would not be surprised if Nikon announces the V3 mirrorless camera by the end of the year with 4k video recording capabilities.
