http://www.canonwatch.com/canon-eos-1d-x-mark-ii-specification-leaked-cw5/ the rumors seems to be pretty certain by now. Seems like a beast for video. Also since the 1dx is getting 4k 60fps it would make sense for canon to get the 5d mark iii 4k 30fps.
That 100% true. You have sharp eyes.
Will try my best.
But remember while the Cinestyle on the 1DC will have the same colours & gradeability & overal stamp, the 1DXII sensor might be different, for example have a higher DR sensor, but it's worth a try anyway to get a sense of our only Log option on the 1DXII. @Andrew Reid Help us out with some Cinestyle/Prolost 1DC grabs in your environment too please if you have the time
