Canon has been quite layed back in the past few years after the splash it did with DSLRs and the 5D Mark II 30p,24p and original 7D offering 720p 60fps in frame rates. This was so las decade and while there have been improvements there has not been an indication of the camera line growing up to develop a true leap in the video mode to EOS users. We have seen a transition to other systems like the Panasonic GH4 Micro 4/3 and Sony NEX series by many video pros looking for better video quality and higher frame rates besides Canon and Nikon bodies.
The video quality while stagnant in Canon and Nikon land has actually increased to 4k in other systems with amazing low light performance like that of the a7s Sony series. Canon seems to have woken up from their slumber with the new Canon 1DX Mk II a Professional answer with a full frame sensor and what looks to be a worthy video mode that is now up to date and competitive with some of the best out there in the under 120fps camp.
