Frankly, there is little chance of this. What you want is a C300 mkii. It does exactly what you say want, you just don't want to pay for one.
If there is a C100mkiii it would most likely be a C200 without RAW/CFAST. A 4K cinema camera with ND filters (hopefully up to the 10 stops found on the C200), xlrs, face detect DPAF with touchscreen, 1080p120, CLOG 1-3, EF mount and which uses the 8 bit internal codecs found on the C200 possibly with 10 bit out over hdmi (probably not sdi).
With the C200 priced at US$7500 this would likely sell for about $5500 and would be a great entry level 4k cinema camera. If you really need 10 bit for all the tv spots you shoot buy a C300, you can afford it. If you only occasionally need that buy a C200 and shoot RAW on the few occasions you need it. The internal 8 bit codecs on the C200 are more than fine for about 98% of web-based stuff.
