There is no PureView without higher FPS video recording
They need to support 720p at 120fps and 1080p at 60fps. Windows Phone 8.1 introduces new video editing features including slow motion effect. This is useless when used on 30fps videos. Also the newer Lumia phones such as 1520 and 930/Icon have enough processing power to achieve the above frame rates. Microsoft needs to support higher frame rate video capture in Windows Phone.
There is this UserVoice entry on this idea but it hasn't got much votes yet. Maybe we can push it upwards?
