I was looking into this the other day and from what I can tell, it doesn't do true 60fps at 720p, if you want that. There is a new SJ5000 that has the much higher framerate (240fps?) so maybe it has true 60fps as well. I believe the lens, some lens adapters, and mounts for GoPro will work with these.
I saw as well that the 60fps at 720p was each frame being shown twice. But I also saw that the SJ5000 is not the next camera in that line and is actually a different manufacturer trying to take advantage of that misleading naming convention.
