More testing with the lastest magic lantern RAW recording option (August 2 2013 version). This time I was able to record between 48 to 60 fps on 1920x500 (squashed version to the 2,39:1 aspect ratio: 1920x804). I really like how crisp and more dinamic it looks compared with the old 720-60p H264 (a comparison soon).
Model: Marielisa Garufi
Music: Tonight (demo version) - Robbie Meza (robbiemeza.com) ft Neka One (guitar solo cortesy of DarienX)

edit: I uploaded a comparison between raw and h264 where you can really see the difference, here: vimeo.com/72133452
