I realise that this suggestion may sound ludicrous, but bear with me...
If there was a way to permanently record black overlays at the top and bottom of the image in camera (since the aspect ratios cannot be modified), then the video files would be substantially smaller and therefore allow for an increase in quality and FPS.
I don't know if there would be a bottleneck at the compression stage, but I'm thinking that this could allow either the Bit rate/FPS to be jacked up and so, overcome the SD card buffer bottleneck on the 600d.
A simple test here showed that h264 files are 25% smaller with 2.4:1 black overlay embedded. If many users are throwing those extra pixels away in post anyway, then it could give a nice quality boost to those of us who can't record 1920x1080 in raw.
