the first 5d video with 60fps?

check out this youtube channel. the titles even say 1080p - 60fps. some info is in japanese, too - i hope the firmware upgrade will have this!

well... seeing as it's timelapse, it's likely a compilation of stills... which could be ordered in post to be whatever you want. For that matter, you could shoot your actors acting really slow and then speed them up 2x if 60fps is that essential
