Honestly Canon is still years ahead of Blackmagic anyway.  The C500's sensor is already in the C100, only the processors to deal with the 4k RAW are different.  If Blackmagic looked like it was going to truly revolutionize anything Canon would just release a version of these same processors (or whatever their next one down the pipeline is) with all the RAW high bitrate stuff enabled.  In a few years it'll be cheaper too.  Meanwhile Canon's colour science, how they deal with IR, egronomics, ect are all very much superior.  Canon's just reading the market, and their entire Cinema line has been super successful and from a business standpoint they're doing what the market wants without breaking the bank producing more than they want.  That's always been the key to their success.  Are they over priced?  Could they do better?  Yes.  But from a research standpoint they're ready for anything the market will demand, probably.
 
I'd say the phenomenon you're describing would probably apply more to something like GoPro, which has carved a niche in the market that Canon would probably have a hard time breaking into, due to all the tech that little company has come up with.  Blackmagic's doing a great thing though, hopefully they'll find their niche too, with their future cameras. But in a world where the F35 used to cost 250,000 and can be bought for 8,000 now, it's easy to assume that in 4 years the script will be flipped completely, again.  How the camera market looks after April will be very interesting.
