I wasn't stating that it *needed* one , I was just following up on what was reported here :
New 5D Mark III Firmware Before the End of May [CR2]
MAY 9, 2012 CANON 5D MARK III, CANON FIRMWARE FOLLOW ON OUR FORUM
There is apparently going to be new 5D Mark III firmware before the end of May. It will address a few bugs, as well as adding some “features”. No mention of what the features might be. It was mentioned there is a possibility of a bug fix firmware update before the “feature” update, a two part strategy if you will.
There have been no mentions of additional features for video.
