I don't have any inside info other than what I can find through searching.
It appears MS will use the open source LibRaw code. Assuming they use the most recent release (v 0.19), the cameras supported can be seen here:
Topaz Labs has a image processing program (Topaz Sudio) that uses LibRaw v.017, which doesn't support the 6D Mark II. LibRaw v 0.19 does.
What would be cool is if there was a way to update the LibRaw version this codec incorporates so folks can update it if they desire.
