Not amazing. Not raw. Not even real.
First of all, it's not amazing because even if this rumor became real some day, all it would do is give DSLRs the same feature that every $200 video camera has had for over a decade: uncompressed video on the out ports. The lowly Canon HV20 had uncompressed 1080p HDMI years ago. Sure, it would be the first on a DSLR, but going from 8-bit compressed to 8-bit uncompressed is not going to solve any of the more serious problems with DSLRS, such as aliasing and skew.
Second, that is no more "raw" than heavily processed TIFF files. It's still going to have the demosiac, color matrix, noise reduction, black clip, gamma, tone curve, color space conversion (with clipping), and all the other in-camera processing applied to it. If it were truly raw, it would be completely separate. The distinction between "raw" and "uncompressed" is lost on CanonRumors editor.
Third, this isn't even real, it's just a rumor. Isn't there some other web site where people can start posts about "canon raw video" and other fairy tales?
