CJK frequency data?

This Rod Sheeter slide deck from a Unicode conference some years ago, which was part of the impetus for the current work, references CJK codepoint frequency data for Korean and Japanese:

Did Google ever make these datasets available somewhere? And if not would they consider making the data available to the working group or is it considered proprietary?
