This story is all over the web, but Petapixel had it right away. A new alpha of Magic Lantern has managed to get 1920×850 RAW video at 24P out of the camera, and it looks much better than the H.264 compressed video and it sounds like it may be better than the Black Magic Camera. As you can see from this Planet5D post on the subject, and you can see their post on the subject as well.
And you can really get into this with the EOS HD post on it.
I am sure that Canon doesn’t want this, as they want you to buy their cine EOS cameras to get RAW capabilities, but it is awesome that Magic Lantern has been able to pull this off!
