No.
This does 4K60p, which gives you 40% speed. If you really, really need super-slow motion for a project at 4K, rent a Phantom for your 1000fps needs. Or a Red monstro which retails at a shitload more more than 15k.
AFAIK no one does FF35 RAW recording at 120p + for 15k. Admittedly, it's much easier to do a higher frame rate if you're using a smaller sensor or lower resolution. Hence the 2K/120 mode.
20% slow motion is only needed for fairly specialised stuff. The vast majority of material is shot at regular frame rate, and most slow motion footage is 40/50% speed. And for a lot of specialised slow motion stuff, 20% is nowhere near slow enough, hence the 1000/2000fps Phantom. Which unless you're made of money you rent.
I guess the next complaint is that this isn't a 50 megapixel stills camera, with stupid Canon forcing you to buy another camera for photography.
