The C300 is seriously over priced. It won't sell well. The Sony FS-100 is definitely in the same ball park and it does 1080p 60 FPS unlike the C300, and it costs 1/3rd as much.
Many cinematographers want a full frame video camera, that's why everyone is waiting for the next 5D. The c300 is 1.5x cropped, which is fine; but full frame video has a unique look.
Plus, for many video shooters such as myself, going back to a video camera ergonomic would really suck. The DSLR form factor is so much more liberating and easy to shoot with than the traditional lunch box style video camera. I can't go back, so I am waiting for the 5D3 or preferable the 4K DSLR video hybrid. I would have no problem paying $5000 for the 4K Hybrid if it's good.
